Checkout UI Exntesion - any way to hide/show based on device type ?

[Sanket_Patel]

Is there a way to fix the position of checkout ui extension ?
We placed it above Pay Now button in checkout designer. It properly displays for desktop but.. for mobile it moved above Order Summary. 

Checkout blocks app : Shopify itself is owner of it. 

On desktop, 

On mobile, it moves itself above Order summary. It should be above "Pay now" button.

@Shopify can any one explain workaround for this ? we like to display our extension-ui simple message above or below "Pay now" button.
