I haven't. Introducing someone to the crypto market is quite hard if you're going to introduce him with those tools as the start. I think it's always best to go the manual method of telling him how to trade manually before using those tools that have been given to you by that platform. There's tradingview which is a good start to help him with charting. Because if there will be a lot of tools as you've mentioned will be shown to him, I think it will just make things complicate as he's still a beginner.
