## A script that modifies Zoom links for the use in browsers, opens it then in a private chromium
##   window and puts the password into the clipboard. If no argument is given the link is taken out
##   of the clipboard.
## The reason behind the choice of Chromium is that my Firefox does weird things when used in
##   scripts and that I wanted to run Zoom separately from my normal Firefox instances.
##   (although this should be solvable by separate Firefox profiles.)
