Due to the current impracticality of in-person presentations at this time, it's never been more important to translate your presentations using video chat apps like Zoom, Facetime, Skype or Telegram. Remember the first rule of presentations: Do not practice on customers. Practice booking the presentation by phone, sending a text reminder, and presenting and I'll play your customer. In addition to invaluable practice and live feedback, you'll be able to work out any technical glitches. Go through your script as many times as it takes to be 100% comfortable and confident in your presentation.
