How can I exclude Facebook Messenger app usage from ScreenTime counting it as Facebook use on Mac?

I have set a time limit with ScreenTime for the usage of Facebook. My phone is properly counting time for the Facebook app and website together and it doesn't disable Messenger when I reach the limit. However, I recently installed Messenger on my Mac and whenever I reach the limit for Facebook, MacOS disables Messenger app too. How can I fix that so that Messenger isn't disabled? I need it as messaging is needed for me to communicate with people, I just want to limit my time scrolling on Facebook timeline?
