Trying to run two Signal Desktops at one machine but different users with both signal-cli

[k4rst3ns]

Hey there,

for my two kids L and M (both without a smartphone) I want to use Signal Desktop on their shared laptop (with both the individual phone numbers on their individual user accounts). By trying this I crushed the first signal-cli instance (by having registered a second signal-cli instance at another user account but on the same machine).
I have a second computer where I could now try to register the first phone number again, but have no clue if it is possible to link that signal-cli instance with the Signal Desktop App on the shared laptop.
Does anybody has an idea, how this could be solved?

Thanks a lot in advance :)
and have a nice day in any case.
