Usability/Accessibility after selecting "Start Sharing" button

[machawk1]

I created an archive in the app (version 0.7.7 from GitHub releases) and selected the "Start Sharing" button. This brings up a message box (title: "Start Sharing?") in the interface with a bit of text.

I began to read the text but after a few second, it disappears without any interaction from my end. If I click the button again, the same behavior occurs.

It might be difficult for some to completely read through this text before it is abruptly closed without any signal as to the reason.
