Error posting to Facebook group

Hi. This my first time using Make, and all I’m trying to do is copy posts from a Discord channel to a Facebook group. But I always get an error, e.g., “The operation failed with an error. Unsupported post request. Object with ID ‘435856428520760’ does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at Graph API - Documentation - Facebook for Developers (100, GraphMethodException)
2:03 PM”.

I’ve played around with it and found that I can copy to a Facebook page, and I’m not sure why it’s different with a group. The profile I am using to post is an admin for the group, so permission should not be a problem.

Do you know what’s going on? Thanks.
