I don't want to make the selections saved in bookmark 1 manually in "App 2" to save it as a bookmark.
I want to share that first bookmark across apps. Just so the user doesn't have to replicate the selections manually and save as a bookmark. Is there any way to copy those selections and create a bookmark with them?
As far as I know, there's no direct way to do this, at least not via the Bookmarks API or with any other method I've encountered before.
Using API, you could presumably apply the bookmark in app 1, pull the selection state, apply the same selections in app 2, and then create a bookmark. That said, if you just need to handle a few bookmarks, it's probably easier to do it manually. Additionally, this will not capture any layout changes, variables, etc.
If you are using Qlik Cloud, you can use the Application Chaining Navigation option of the Button object to switch from App1 to App2, which I believe brings along current selections.
