My co-worker and I have different prefect cloud accounts. How can I grant permission to my co-worker to view my flow run, or execute flow I registered?

do you mean it for Prefect 1.0 and cloud.prefect.io? asking just to be sure because we now also have Prefect 2.0 and beta.prefect.io (Cloud 2.0)

Prefect 1.0 and cloud.prefect.io

Are you in different tenants or the same?

you should be able to invite users through https://cloud.prefect.io/team/members

Got it! we are still at free plan, need to upgrade for this capability
