How to add "Use ctrl + scroll to zoom" like Google Maps for interactive embed

Site URL: https://www.coorlasarch.com

Is it possible to add a "Use ctrl + scroll to zoom" (Similar to google maps embed) on other 3rd party embeds?

I have 360 spherical views on my website, and when users scroll through the interactive 360 view (embed), they tend to get caught in a virtual world.

Perhaps this is only achievable through the 360 View hosts code?

I found this from the the 3rd party host:

add "?wheel=false" to the end of the html embed code

which worked to stop the scrolling, but I'm still looking for a mouseover css that responds only to these embeds with a crosshair arrow or something to indicate that it's interactive.
