I would like to know if this is possible, I have a Button that I would like to use, but The Chromecast Code Guides are way too Unorganized and Hard to Understand.
Wix won’t help you with Google ChromeCast as that is another product from another company.
Although I am pretty sure that if you want to use Google Chromecast then you must use the icons that are associated with it and not your own customized ones.

If you are trying to use it within your Wix Editor, then you will need to import it through their own API.
