Vegas does not work anymore? Kali 2020

I’m currently involved in The Complete Ethical Hacking v10 with professor Mohamed Atef, there are many things that he skips and i would like to know if there is a way to comunicate directly with the facilitator… Also the Vegas software he uses in linux for an important Web App Vulnerability Analisys is seems like is not longer working with Kali 2020 and i would like to know the alternatives.
