How to resolve Token Error 400

When generating the Token and running, we received the following error:
Forms 400 {"error":{"message":"Any of the pages_read_engagement, pages_manage_metadata,\n pages_read_user_content, pages_manage_ads, pages_show_list or\n pages_messaging permission(s) must be granted before impersonating a\n user's page.","type":"OAuthException","code":190,"fbtrace_id":"A-MxMGyeKy_vgi4P6Tsi8B8"}}
However, all permissions requested in the error were already selected when generating the Token. The part "permissions must be granted must be granted before impersonating the user page" doesn't tell me what should be done.
