🔥[🐛] [expo][plugin] Does not add the Background Modes capabilities

[AntoineThibi]

Issue

The current documentation of react-native-firebase/messaging suggests enabling Background Modes capabilities for iOS as part of the setup process (see iOS Setup). However, when integrating the @react-native-firebase/messaging plugin via Expo, the Background Modes are not automatically added.

Expected Behavior:

The documentation or the config plugin should align with the actual behavior of the package when used with Expo. If the Expo plugin @react-native-firebase/messaging does not automatically handle the addition of Background Modes, this discrepancy should be clearly mentioned in the documentation, along with guidance on how to manually set up Background Modes for iOS when using Expo.

Steps to Reproduce:

Follow the instructions for setting up react-native-firebase/messaging on iOS as per the official documentation. Add the @react-native-firebase/messaging plugin via Expo. Observe that backgroundModes are not added automatically as part of this process.

Suggested Solution:

Best solution : updating the expo plugin to add those Background modes (if you agree with the issue, I can make a PR to add it)

Quick fix : changing the documentation, to also tell the user to add these capabilities :

// app.json
{
  "expo": {
    "ios": {
      "infoPlist": {
        "UIBackgroundModes": ["fetch", "remote-notification"]
      }
    }
  }
}

Hi there - with apologies - we do have Expo support in the repo but it is community-provided. I do not personally use Expo so I will not be able to help here.

Hopefully someone that uses this library + Expo can step in to offer a solution
