Crashlytics Compatibility with Expo Development Build? Possible?

Hello everyone.

I appreciate any help I can get with this asap, since I am spending wayyyy too much time on this stupid problem. I have been building my app and realized that I can’t use Firebase Analytics unless I move to a development build. So I did make sure that everything I want to use is installed, this is just my firebase stack that I had going before I did a development build:

"@react-native-firebase/analytics": "^18.3.2",
"@react-native-firebase/app": "^18.3.2",
"@react-native-firebase/auth": "^18.3.1",
"@react-native-firebase/crashlytics": "^18.3.1",
"@react-native-firebase/perf": "^18.3.1",
"@react-native-google-signin/google-signin": "^10.0.1",

I am running all the newest packages for everything Expo related. Although when I try and run my development build on the emulator it crashes. I have been struggling hard with this, as when I check the adb logcat it seems to be related to Crashlytics. When I check the Crashlytics documentation it seems like I need to add some things to the build.gradle, but I cannot find that, and I am pretty sure that it may not be doable because I am not going full bare workflow, I just did a development build. Correct?

Does this mean that I can’t actually use Crashlytics in the current build I have done then? I did an EAS build to get things going. I don’t really want to eject to a bare workflow, as I am pretty new and that would be a significant learning curve addition on-top of everything else. I like the aspects that Expo offers in the managed workflow.

I have been getting along very well until this part, and can’t seem to get past it. If I am not able to add Crashlytics to my project I would rather just know that ahead of time, vs keeping wasting time on it. Also, it seems like Analytics wouldn’t have that same problem though at least, would it?

These are the other parts of my package.json to give you an idea of what I set-up:
