GTM Spotify tag accessibility issue

[tieneke-amazing-bv]

I am conducting a WCAG check of our site, which we are failing due to an issue with the GTM Spotify tag. The particular issue is around adding aria-hidden="true" attribute to the Spotify iframe. This way you tell screenreaders this is not a content element that needs to be read out loud, which helps improve accessibility for users relying on assistive technologies. 

Thanks!
