Transfering website domain with google workspace to square space

Hi,

We have website and a domain with another provider and we are thinking to moving to squarespace for more ease of use.

Our domain has already a google workspace with several e-mail adresses, how would the transfer process in that case ? Will our google mails stop working ?

Thanks

Also, we upload sometimes some webgl builds from Unity game engine on our website for client review (we are a video game studio) is this something possible with squarespace ?
