Handsfree Voice Assisted Dialing

We're an organization of recruiters and sales staff that are now 90% working from home. During the pandemic we all started using our cell phones - because we hadn't migrated to Ring Central (which we did Summer 2021). Staff are used to saying "Siri - please call...". We're trying to get our staff to only use the Ring Central Mobile app - but they miss handsfree virtual assistant dialing. I'm sure this presents complications with Siri and Google but here it is - that is the request. Cheers and thank you!
