\shared-content not working with images in template

What I did: i created a template that has the \shared-content placeholder in it.
In another app, i shared a picture to the agenda app, selecting my template.

What happened: The entry was created, other placeholders (\now) work, but no picture.

What I expected: i expected the picture, if i share a simple text it works. Does the \shared-content placeholder support pictures?

Things that might be helpful to know (Agenda version, OS and model, etc):
Agende 13.1.1, iOS 14.7.1 iPad Pro 11“ 3. Gen
