To add a Facebook Messenger bot you have to connect using your Facebook account. The process is very simple. After clicking the "Continue with Facebook" button you are presented with this window
After continuing, you have to choose the Facebook Page with which the bot is associated
Afterwards we suggest leaving the switch to YES
And lastly you can confirm that you have connected your Facebook account to Enchatted
Back in the Testing Platform you just have to pick from the dropdown the appropriate page and you can move on to the final step of the bot connection.
