Should I complete the "Verify Domain" process for several differnt Atlassain orgs under a single IdP

[Kevin R Moist]

Hello, we have several Atlassian organizations (all with different name spaces) and all are each managed by separate departments/administrators. Azure IdP is configured so of course all users access the different Atlassian organizations via SSO. From what a can tell (I do not have the access to all yet) some if not all Atlassian Organizations have NOT completed the "Verify Domain" process. Do each of the different Atlassian Orgs perform the verify domain process separately or does only one org need to perform? Or is this not possible? Once the different Atlassian Org domain(s) have been verified, does this mean all accounts as part of the separate Atlassian Orgs can be managed centrally or still just under the individual orgs?
