Is there a way to install my supported Oculus Gear VR games onto my Quest 2 like we were able to install them on the original Quest?

Isit possible, with the Quest 2, to cast to a Chromecast enabled device whileplaying a Rift/Steam game on my computer using Virtual Desktop since both operationswill be using my Wi-Fi network?

Does the Oculus Quest 2 Elite Strap with battery have a port to plug in the Oculus Link cable since the Quest 2 port is taken up by the Elite Strap battery connector?
