Windows App - Account Switching Based on Login

[BSBESIT]

I have a fleet of fire trucks and ambulances that change type designation from time to time. Each designation has an extension and I need that designation to populate the correct account for the phone to be online when they login. How could I go about switching from 3CX account to 3CX account without a folder of account files to select from that the person would have to drag and drop onto the 3cx app? They need something fully automated so whatever I need to do I can do but it has to be automatic cause… the guys are lazy when it comes to the computers.

UPDATE:
I was not specific in my question and I apologize for that. There is only 1 "account" but they login to our system application which has a .txt file which changes to the current logged in user on that app. When that a user changes the login on the application, I have a service running that will then change the 3CX current user to the new user that is found in the txt file. I need a way to inject the user I want to login to the 3CX app so someone suggested:

3CXDesktopApp.exe tcx+app:<HTTP/S link of QR code>

This is good but I need to know where the "HTTP/S link of QR code" is stored.

when they login

...to Windows? Each Windows user account has its own install of the Desktop App so would be its own extension. (perhaps, make the desktop background show a label or color for which account they're in)

The QR itself shows in the management console on each user's page, to decode manually. I've occasionally seen other posts looking for the URL but don't recall an answer offhand. I'd guess it's probably buried in the database somewhere, if it's not generated.
