Hi Folks.
I have "LIST A" on SP Online and started creating a Power Apps form for that list but I did not use "Power Apps > Customize Form" from the List menu.I first created a Custom form in Power Apps Studio using "LIST A" as data source. Everything is working properly but now I need to connect this APP, to the NEW button on SharePoint List menu.Any tip on how to do that?Best.
This is impossible. You create app from blank in PowerApps Studio is a standalone canvas app.
If you need to customize a SP from, you must start from Sharepoint list -> customize form, in which case the app is created based on SharePoint integration.
You won't be able to connect the custom power app as your list form but if your business scenario needs it, you can add a new command in SharePoint command set (a custom button) using SPFx and hide the existing New button (using application customizer).
