Concerns and Clarifications on Facebook App Setup

I have followed the Facebook app setup guide on chatwoot , however I haven't made the request for app review yet because the inbox is not set up yet, so I nor the reviere will be able to test the app. and I think that if they are not able to test it, they don't approve the permissions.
Also I have a doubt, if the inbox is only for an instagram and Facebook page that I own do I still need the advanced permissions? I thought it was only for when one is using the technology with multiple accounts on behalf of other businesses .
I am reading correctly the docs? ( https://developers.facebook.com/docs/graph-api/overview/access-levels/ )
"If your app will only be used by people who have a role on it, the permissions and features your app requires will only need Standard Access. If your app will be used by people who do not have a role on it, the permissions and features that your app requires will need Advanced Access."

you should be able to test with out getting the approvval

I have replied to the github ticket
