Bug description

Looks like there is no support to share multiple images with text.
(someone mentioned behaviour with mixed image/text data before https://community.signalusers.org/t/signal-as-sharetarget-should-support-mixed-content/47745)
UnresolvedShareData class has ExternalMultiShare type without text property

Steps to reproduce

Share multiple images with text from another app (Intent.ACTION_SEND_MULTIPLE + Intent.EXTRA_TEXT)

Actual result: Intent error message or only text sharing (depends on intent configuration)
Expected result: Application will open image edit screen(like multiple uris sharing) + copy text to EditText field
