chore: Create a video tutorial of configuring Facebook in Chatwoot end to end

[sojan-official]

@pranavrajs could you please also create some video for self hosted configuration of FB creds? I tried to integrate but it is not clear what all permissions must be given to the business app created on developers dashboard ? A details video on facebook setup for chatwoot would be really beneficial. Thanks for wonderful product. It will be good if you can maintain separate code for community edition and enterprise edition.
