Modify Image Picker Selected Photos Permission manually

Thank you for your amazing work. We are using Chatto for chat module in our application. Recenlty we have been advised to review Photos/Gallery Permission Popup.
Steps to reproduce:

1. Close and reopen app
2. Open chat
3. Click the camera button at the lower left of the screen (right next to the keyboard button)
4. Select “Keep current selection”

From this point, if a member wants to add more photos to the current selection, they have no choice but to close and reopen the app. again popup will appear and select add more photos

**Is there a way we can show permissions every time we open up the chat screen instead of seeing this after killing and relaunching app?**

Start by reproducing the permission flow described: reopen the app, open chat, tap the camera button, and choose “Keep current selection.” Investigate the chat screen's image-picker entry point and verify that users can reopen the permission choice to add photos without killing and relaunching the app.
