Hello @Ity ,
Thanks for reaching out.
It depends on how the application is registered, for an example: if you create an app using an Microsoft Account (MSA) e.g. outlook/hotmail, then it will be published in MSA tenant (MSA tenant GUID:9188040d-6c67-4c5b-b112-36a304b66dad and Name: microsoftaccounts.onmicrosoft.com).
In other case, lets say there are couple of apps, registered in microsoftaccounts.onmicrosoft.com (registered by users with personal Microsoft accounts) as multi-tenant apps so when one of your organization's users try to access them, then this would also create an app entry with appOwnerOrganizationId:9188040d-6c67-4c5b-b112-36a304b66dad
.

Hope this helps.
