How to view event parameters from Firebase console

Question

I have just started using Firebase for my app analytics and I'm having some issues trying to view the parameters associated with my events. Upon logging into the console, selecting my app, then I select the iOS version and I'm presented with the dashboard. All of that looks good. Then I select the Events tab, and I see a list of all events that my app has logged. Again, this is all good. However, I want to be able to drill down and see reports based on the parameters that were passed with those events. in my iOS code I have the following:

[FIRAnalytics logEventWithName:kFIREventSelectContent parameters:@{
    kFIRParameterItemID:@"some_item_id",
    kFIRParameterContentType:@"some_content_type"
}];

I want to be able to see how many of these "select_content" events were from a particular "content_type". But I cannot figure out how to do that.

I tried creating an Audience using "content_type" that I know I tested days ago, but my number of users is always at 0. So I'm at a loss...how the heck do you see analytics for events based on the parameters that were supplied?

Honestly, the answer here didn't help me at all. I finally figured out that you have to manually add custom parameter reporting to each event. Here's a link to the docs.

And I guess in case this link dies, I'll add the steps below. This is just copy paste from the link.

Custom-parameter reporting Define custom parameters for your events.

Google Analytics for Firebase lets you specify up to 25 custom parameters per event (Android or iOS).

You can also identify up to 50 custom event parameters per project (40 numeric and 10 textual) to include in reporting by registering those parameters with their corresponding events. Once you register your custom parameters, Google Analytics for Firebase displays a corresponding data card in each related event-detail report.

Each parameter that you specify counts toward the project limit of 50. For example, if you specify the same parameter for 3 different events, then that counts as 3 of your 50.

To register custom parameters for an event:

In Analytics for Firebase, navigate to your app.
Click Events.
In the row for the event you want to modify, click More > Edit parameter reporting.
In the Enter parameter name field, enter the name of the parameter you'd like to register.
If a match is found, select it in the list and click ADD.
If no match is found, click ADD.
Set the Type field to Text or Number. For numeric parameters, set the Unit of Measurement field.
Click SAVE, then click CONFIRM.

On the Events page, any event with registered parameters has a gray box next to the event name with the number of registered parameters for that event.

To edit registered parameters:

In the row for the event, click More > Edit parameter reporting.
Add new parameters per the instructions above, or click Delete to remove a parameter.
Click SAVE, then click CONFIRM.

The per-app count for registered parameters appears at the bottom of the list of parameters. As you enter parameters, the count updates. When the quota has been reached (50), that number appears in red, indicating that you cannot register any more.

When you register custom parameters, a data card for each parameter is added to the related event-detail report. However, it may take up to 24 hours for the data card to appear.
