anyone tried virtual speech therapy?

Due to the rise in covid in our area and being I’m pregnant we wanted to try out some speech therapy virtually

My sons almost 3 now. 100% comprehends and says a lot of words. But doesn’t say any sentences and still uses some gibberish. Uses gestures when wants something rather than asking.

Wanted to give it a go and if it doesn’t hold his attention we will have to do it in person

Was just wondering if anyone tried this? Thx ☺️
