I plan to use a phrase like 'lets connect on Element'.

Element is a much better name than Riot. Lot less of a hard sell to convert normies.

Yeah, I guess the polysyllable "hop on a Zoom call" has already entered the corporate lexicon, and "hop an an Element call" could just as easily displace it.

I’ll zoom you also sounds weird unless you know zoom is a telecommunication app, and it sounded weird until people started using it. “I’ll start an Element call with you” won’t sound weird after people start using it.

"I'll Riot you" is also a non-sequitur at best

Perhaps less confusing than Signalling someone :)

You shouldn't say that anyway, since the protocol is called Matrix
