@juliapiers, it’s common to pass parameters while launching apps. If you are on Linux just have a look into /usr/share/applications/. There are a lot of .desktop files, some of them pass parameters into a binary. And the Desktop Icons you see (located in ~/Desktop/) do this as well.
I implemented Zoom on a Thin Client (which is a read only FS, no persistency), so I have to configure the binary each time I launch it. And I have done it with Teams as well (using this parameter --proxy-server=proxyserver:proxyport).
So the question is: is there a parameter (or a conf file) where I can set this values. I found some ressources stating to use a zoomus.conf file, but it isn’t used as far as I can see.
