Agent documentation is not confirmed by the reality

I tried to use the agent module in an unauthenticated scenario as described here agents - Base44 Support Documentation that says “This module is available to use with a client in all authentication modes:

• Anonymous or User authentication (base44.agents): Access is scoped to the current user’s permissions. Anonymous users can create conversations but can’t retrieve them later, while authenticated users can access conversations they created.

• Service role authentication (base44.asServiceRole.agents): Operations have elevated admin-level permissions. Can access all conversations that the app’s admin role has access to.”

but the reality is that I get errors like this

which seems to tell that only authenticated users can create conversations, anybody tried already something similar?
