Not sure why you wanted to set up an account in your name if it was really for a property management business... Always makes me sad when I see the proof that Airbnb is flooded with professional listings, for me personally definitely not what the platform is all about!
But then I take it the profile is also linked to your business email address, as long as they keep that one running and change the password on the account it could still work! I don't see any host reviews, so you haven't used it for personal travels. Just go into the area where you can edit the profile. Not sure if you can change the primary email address if it is your personal one, but it's up to you if you do that. If your company is happy with just turning off all the email notifications....
Good luck with your new job, @Allan28
