There are two types of PowerApps: Form and Canvas. If you just modified the list item view form you will see a lot of limitations on available functionality. So, you might want to create a Canvas app instead. If you created the Canvas type PowerApp it will always be opened from the PowerApp site. What if you want your users to a user that PowerApp when they click on the New Item or Edit buttons in the list from SharePoint Online?
Use The PowerShell Script Provided Below
Pre-requisitions:- You need to have at least site collection admin permissions
