There is a similar issue https://github.com/MonitorControl/MonitorControl/issues/258, so I'll close this one as a duplicate.

Sorry to say, but as of now there is no known way to tap to that slider as it is a protected part of the OS so this issue will probably not be solved anytime soon or ever. :(
