I believe it should be possible, but then you need to add multiple tenantid's to cognito userattribute. For example an array or string with commas as seperators. In your application you can to the validation
I don't think this works exactly. Because user needs to have access to specific projects within a company. With multiple tenant ids 2 users within the same user group will have access to all projects within the tenant that is shared to the user group. See the image for an example of what is needed. dev-to-uploads.s3.amazonaws.com/i/...
I don't think that works because you can only have 500 cognito user groups and users will need to have access to specific projects so each project's access will need their own cognito group I think. I have updated the user access diagram maybe that will make it more clear
There can also be a user 3 in above diagram that is a freelancer in both Company 1 & 2 and has access to only project A & C

The number of Cognito groups now is 10,000.
And a user can belong to 100 groups.
