You can give a try to gnome-network-displays, installable through means of Flatpak system. Keep in mind that it's considered "experimental" by its authors, meaning it may not work at all for you. Also I don't know how it will be on Ubuntu 20.04 LTS, you'd better be on Ubuntu 21.04 (in beta as of my writing) cause it has several bugfixes and features relevant here.

There's a complete answer I've written on flatpak+gnome displays for samsung smart tv that could be a duplicate:

Connect your pc or laptop to your smart-tv with wifi and then go to display in settings and then customize your settings such like which display will be your primary screen and other settings similar to Windows.
