How to connect JItsi video links back to app

I have integrated JITSI API for my flutter app to allow users to join / host video conferences in real-time. I was wondering if there was a way to link users back to my app when they share the video links. Currently, they are taken to the video conference page and after they are directed to JITSI, I would like for them to be directed to a signup page for my app instead. Has anyone figured this out yet?

What kind of links are those? Can you provide an example?
