Separate my Gmail accoutns

I have two gmail accounts that I use as my main accounts. One is personal, one is meant to be more professional. For some reason, they are connected and emails, such as for professional Zoom meetings, seem to go to my personal gmail, even when I never have given that out to someone.

What can I do to prevent this? My personal account is not one I check very often so I miss these invites, and as I said, would rather get them, as they are for work, to go to an email address I use for work.

Thanks for your help.
