I have a powerapp new form with SharePoint as the datasource. In the newform, documents which user uploads in attachment control gets stored in document library.
The attachment field only allows ppt/doc file types. I have added a validation for the same in attachment control.
I also need to restrict the same in Upload Document screen, where user cant even upload other file types. May i know how to achieve this? Screenshot included below. Instead of All Files, it should only show PPT or docx
