fullscreen icon not present on mobile on iphone

Hello,
I just noticed that the “go fullscreen” icon is not present on iphone. It displays correctly on android (and desktops).
How can we enable in for iphone? or is this an apple limitation?
Here are the screenshots:

Hi there,

Thanks for reaching out, yes, that icon is not available on Apple devices unfortunately, you can choose to display/hide these icons by default by referring to this knowledge base article here.

Cheers,
