View in AR button not showing in App Builder iframe embed

I have created a App for a model in shapediver and trying to embed in a webpage, for some reason the view in AR is not showing.

This is the app: ShapeDiver App Builder

This is the web page: https://sierralogandtimber.com/sequoia/

Please let me know if there is a way to show the view in AR in iframe embed.

The model you linked in your post does not seem to work anymore, but I worked with this other one:

I enabled AR in the model settings:

I also switched the units to inches, but feel free to adapt if those are not the right units.

As far as I can see, the AR button is now shown in the App, also from the model embedded in your website:

Let me know if you have further questions.
