Step 1: Go to the Integrations section, located in the right-hand menu. Then, select the pencil icon next to the Facebook Integration.

Step 2: Click on "Login with Facebook". You will be redirected to the Facebook website, where you'll need to follow the steps to accept the integration.

Step 3: Choose which Business Account you want to use for the integration. Change the active status to "True" and don't forget to click on "Apply new settings".

Note: If you have more than one Business Account connected to your Facebook Account, you have to create a separate integration for each one.

There you go, you have successfully set up the integration!
