Issue Summary: Meta is incorrectly sending a messaging webhook instead of a standby webhook to iDesk when a button is clicked, even though iDesk does not have thread control as the secondary receiver.
Steps to Reproduce: 1. Ensure iDesk is set as the secondary receiver in Meta's Messenger handover protocol. 2. Transfer thread control to the primary receiver (e.g., another bot or system). 3. Perform a button click action on the Messenger UI. 4. Observe that Meta sends a messaging webhook instead of the expected standby webhook to iDesk.
Expected Behavior: Since iDesk does not have thread control, it should receive a standby webhook for button clicks.
Actual Behavior: iDesk receives a messaging webhook instead, which is incorrect behavior.
Suggested Fix: Meta should ensure that button click events are sent to the standby webhook when iDesk is the secondary receiver without thread control.

The app reviewer is asking for test facebook credentials to test the account. When I go to create a test user it says that Facebook has disabled the ability to create a test user. Has anyone run into this. Is the solution then to create a dummy facebook account add it as a friend and then as a test in the app role section. Would greatly appreciate any help on resolving this matter. I brought this issue up in the review but they did not address the current inablity to create test users.
