I thought I mentioned it already in an email to you, but maybe not? The challenge is that the “old” Click approach works only with Chrome manifest V2. This is no longer technically with the manifest V3 changes in Chrome. This is beyond our control. Of course, until early(?) 2023 you are welcome to use the old version. Just at some point Google (not we!) will turn it off.
As for the browser having to stay in the foreground for XClick. That is true. If this is a problem, we usually recommend to run the RPA automation in a virtual machine. Even a small and free Linux Virtual Box would do.
We also dealing with issues where the scripts suddenly stops executing for now reason with no warning messages or disconnects more frequently from the browser tab and stops.
That is something we are investigating. If this is an issue for you, I recommend you stay on V6.2.8 for now, or add some retry logic to the calling script. I totally agree, this issue must be fixed.
