On my new-ish Android phone, I can't select files (e.g. from a gallery or from a filemanager) when contacting support. It will only provide me with the camera or "genius scan" (a receipt scanning app, so also a camera).
This way I cannot send screenshots when reporting issues/bugs.
The same issue appears when adding an attachment to a transaction, for example (so it's not limited to just the support part)
The Bunq app has both storage and camera permissions.
This is with a (rather) stock android 10 (google pixel)
Other apps (e.g. whatsapp) will allow me to select, e.g., a screenshot through other apps
