User is not allowed to send invitations for this team

Where can I edit in the web console to allow users to invite? or in the code if possible?

Is the user inside the team?

yes sir.

Maybe it needs to role Owner to be able to do that

An alternative is using an appwrite function

how to add user to be an owner of existing team?

any idea sir @D5 ?

Change/add the role of the user in the team to "Owner"

yes. it works already.

So does that solve it?

Note that the user will be the owner, meaning it can have more permissions than average user (can delete/modify the team if I remember it well). If you don't want that, use an appwrite function to generate the invitation

yes.
