Adobe Express - Schedule to additional pages/accounts

Hi - looking to link my scheduler to a second facebook/instagram account. Every time I go to link it just links my 'Primary Business' page. I want to link my 'Secondary Business' to it also so I can post and schedule differently. So now I can be connected to my 'Primary Business' page 3 times, but not my 'Secondary Business.

Do I need to create two meta/facebook accounts and login to them separately? Feels like it's something that should work without having to do that.
