Is it possible to add attributes to Shopify APP iframe?

[konrado]

I am looking for a way to add extra attributes to Shopify APP iframe - is there any way to do this?

Example use-case: I want to add HotJar tracking for an APP working inside Shopify Admin iFrame - and to make that possible - according to HotJar docs: https://help.hotjar.com/hc/en-us/articles/115011624347-Can-I-Track-iframes-Inside-Heatmaps-and-Recor...- there is requirement to add data-hj-allow-iframe="" to parent iFrame. 

Thanks in advance for any suggestions.
