If you got a message about needing additional permissions for an Instagram integration, the admin or owner of your Facebook business page needs to give you permissions OR someone who has the right permissions needs to connect the account.
If the admin wants to give you the right permissions, here is how to do that.
Log into your Facebook account and click into the Meta business suite. You can find that by clicking on your profile photo in the upper right corner of your screen and the option will be in the menu that appears
Next, click "Settings" (in the lower left corner of your screen) and then click "Pages" (found under the Accounts section of the left menu)
Then click the "Manage" button you see to the right of the person's name you are trying to adjust permissions for
Finish by giving them "Full control". If you don't want to do that, the minimum requirement for the integration is permissions on Content and Insights
Hit "Save" and the account should be good to connect the integration to Enji
