I have Google Analytics set up for my React Native app (iOS/Android). I have a custom event create_item with a custom dimension category.
In the Google Analytics dashboard under Engagement > Events > create_item, I can see in the EVENTS IN LAST 30 MINUTES panel that the custom dimensions are being passed to GA correctly.
How can I see the breakdown of category for this create_item event (ideally something like a pie chart or bar chart), or custom dimensions that happened over 30 minutes ago? I've been trying and failing to set it up from the Explorations > Free Form tab.
