Why can't I download Forza Horizon 5 from the XBOX App?

All of my Microsoft and Xbox games are downloaded on my external drive including the previous Horizon, which is Forza Horizon 4. I changed where new apps are stored when downloaded from the Microsoft store to my external drive but it still wont download Forza Horizon 5 to my external drive. On the Xbox app it wont show my external drive as an option to download to. I am able to download any game from the Microsoft store and Xbox app to my external drive except Forza Horizon 5.

I meant that game is available on store but can't be downloaded without xbox app. Its Forza Horizon 5 btw.

This is what helped me and got Forza to download.
1. Go into the Microsoft Store and search Forza Horizon 5 Standard Edition.
2. Next you want to click on Forza Horizon 5 Standard Edition and you want to click Install from the Xbox app.
3. This will take you to the Xbox app and when it takes you to the Forza game scroll down and look at the tab named "Included in this bundle" And click Forza Horizon 5.
4. This should take you to the regular Forza Horizon 5 game rather than the Standard Edition, And then you want to click install and this should download the game.

Hope this helps have a good day!

If the last suggestions didn't help from Jesse here is mine that helped me.
