Multitenancy don't work with Tenants having same Groups

I have the following Scenario with Camunda Multitenancy:
A user who belongs to group group1 and group2 and has tenant1 as a tenant can view and execute the tasks of Tenant2 ! This contradicts the multitenancy principle!
In my example, Tenant2 also has the same group names as Tenant1.
Is it the reason for this side effect in Multitenancy?
Can’t tenants have the same group names?

Hi @ilyas,

Multi-Tenancy has nothing to do with authorization. It is just about data isolation.

Only users and groups can be granted access through authorization module.

So having groups added to both tenants means members of both groups can access resources belong to both tenants but as per granted access to the groups and users.
