Embedding WhatsApp group discussion into website

WhatsApp groups are popular today. I thought to embed WhatsApp group into a website. Searched on www.remarpro.com repository but could not find anything. There are many plugins related to WhatsApp chat but none I could locate of WhatsApp group. It would help if someone point to a plugin if already there.

I came across this https://youtu.be/lCmoay0G86M?si=drAOFWvZ-Xt8Ts6F and believe successful implementation could lead me accomplish my goal. As WhatsApp group content are limited to be accessible to its members, I believe the content will not be public. Am I correct or missing something? Also any additional guidance/tips highly appreciated.
