I have games purchased through Steam such as 7th Guest VR and Timelock VR.

I can find 7th Guest VR through Applab but it wants me to purchase it again for $29.99. I have no option to sideload it that I can see. I cannot even find Timelock VR in applab.

I cannot find any way to sideload games that I have installed onto my PC to my Quest 2 headset.

Such as explained in the below video at the 7 minute mark. https://www.youtube.com/watch?v=HD1gCEvV8N8&t=452s
