Need help: In Chat module , Get different apps screen link into another app

so there are two apps A and B
when person a sends a message on app A, person B get’s the update but you want to provide a link that takes person B to the chat right?
Would they go to the current chat or to the chat ID?
I haven’t done this before so I’m not sure if this will work.

But you can generate URL for each row, using the row ID. On both apps make a this row URL column
for app B when a chat is engaged send the user the URL

you can get a row URL using the rowID, it’s called deep links, then you can have an action or write the URL to your column
