Hi,
I have a rather simple problem, but as I am very new to the entire Power Apps-world I can't seem to get it to work properly.
I have a file gallery based on an empty Vertical Gallery. It correctly shows the three demo-files I have.
I then added a checkbox to the first file in the list, and it gets put on all the other rows as well.

Now I want to add a button which copies the selected files from Sharepoint A to Sharepoint B.
This is where I get no further.
I guess I somehow must collect the document id's, send them to a flow (maybe) which in turn copies the files... But I have no idea how to send these id's to the flow.
