CreateResourcePolicyStatement

Adds a new resource policy statement to a bot or bot alias. If a resource policy exists, the statement is added to the current resource policy. If a policy doesn't exist, a new policy is created.

You can't create a resource policy statement that allows cross-account access.

You need to add the CreateResourcePolicy or UpdateResourcePolicy action to the bot role in order to call the API.
