No Eevee cursor on Snap apps. How to solve (reuploaded)

[Desire_Kyuyrii]

I managed to launch budgie-common-themes and linux-mint-themes on Snapcraft, and I already made a post asking for help to get the auto connection, I just hope someone sees it.

Auto-connect for budgie-common-themes and linux-mint-themes snaps

I need the Snap budgie-common-themes, flugir-budgie-theme, pocillo-icon-theme and linux-mint-themes to automatically connect to apps that have the gtk-2-themes, gtk-3-themes and icon-themes plugs. What is needed to achieve auto-connection?
