Need for a "favorites" button in the Xbox Cloud Game app

My name is Fernando I'm an independent consultant, I'm happy to help

Xbox backwards compatibility continues to expand. You can play more and more Xbox 360 disc and digital games on next-generation consoles—even some of your favorite Original Xbox titles. Get them from the Microsoft Store or pop in your old disc.
To find out if your games are backward compatible, check your game library. Go to My Games & Apps > Full Library > Purchased Games, select the Filter button, then toggle the All console types filter to Xbox 360 and Xbox or Xbox One.
You'll need to press the Menu  and View s buttons simultaneously to access the Xbox 360 guide and console-specific features like achievements, group chats, or friend requests while you're playing your Xbox 360 compatible game.
To continue playing an Xbox 360 game on your new console, save it to the cloud. If you're already using cloud save games, you're good to go. If your game save is stored on Xbox 360 only, you will need to upload it to the cloud.

Hope I helped and see you soon

Hi, I'm sorry that solution wasn't the right one, Yes, you should be able to download a cloud save game that has "Xbox cloud saves" and "Xbox game anywhere". However, if you no longer have access to the game, you may not be able to download the cloud save.

In order to reach the solution, follow the following steps.

Open the Xbox app on your PC.

Click the "Games" tab.

Find the game you want to download the cloud save.

Click the "Options" button.

Select "Manage saved files."

Select the cloud save you want to download.

Click the "Download" button.

Let me know if you need anything else or if your problem continues.

Sincerely.
Marvina.

Go to My Games & Apps>Full Library>Xbox Game Pass and set the filter to “Cloud gaming” to explore. Next, click the “Play” button with the cloud icon and get to gaming

I tried all 3 suggestions. Currently, the regular game pass app says "install to" for cloud games, and the game pass beta app has the "play" button dimmed for cloud games and doesn't work.
