I forgot to bookmark my resource for allowing users to download file contents from the attachments column.
Launch($"{frm_envurl}api/data/v9.2/fccbh_documentattachments({ThisItem.'Document Attachment'})/fccbh_attach_file/$value");
Using this, I'm able to download the files from the record but my end users are not able to even if they uploaded the files. I believe this is a function of the web Api, but I'm not sure where the permissions are managed.
the following resolved my issue
Download Dataverse attachments from a Canvas Power App (linkedin.com)
Hello,
Double check if your users have permission for the particular record of your custom "fccbh_documentattachment" entity. As far as I remember, file fields do not have special permission required to read unless there is a Field Level Security around the field.
