TAG Heuer Connected E1 help

Hello
I bought a used tag connected e1.
I am having problems to upload Watch faces from the app to my tag e1. I am wondering if I have the correct app.
I have an iPhone so do I need the connected modulair app? Because I was using the connected app … but then when I go to watch faces I can not upload them. When I say connect it sends me to wear os where I can choose some Watch faces but not all … like the Porsche one is not showing or orbital is not showing ..,
And do I need to update something on the Watch itself ? Like in google play store on the Watch ?

Thanks in advance

Although the E1 (which I have) will not receive the latest Wear OS updates that newer models will (e.g., the E3, which I also have), it does help if you install all the updates available from the Play Store (My Apps) in the watch.
