Use this option to specify that anything containing “(Meeting) | Microsoft
Teams” (which should be in the title of MS Teams when in a meeting) should have
100% opacity, and also that anything containing “freerdp” should have 100%
opacity.
For Teams I really only need it to be opaque once a meeting starts, I don't care
the rest of the time.
For XFreeRDP I've tried matching on ‘class_g’, ‘name’, nothing seems to work.
Using ‘opacity-rule’ finally seems to have an effect.
The rules both use ‘*’ to match anywhere in the name, and ‘?’ to specify that
the match should be case-insensitive.
