I have used the same technique for some years now, using my personal gmail account. I embed the calendar inside my own website, allowing me to switch to other platforms without changing the line (https://wiki.alcidesfonseca.com/about/meet/). As a professor with many different responsibilities, this helps me a lot. First of all, it moves the calendar battleship effort to the other person. I barely have to think about it. The only downside is that I might like to have full empty day (they are not exactly empty, but days I can devote to research on my own, usually at home). Sometimes I try to ask people to reschedule in order to minimize chaos in my calendar.
