Jitsi meet embed with iframe external api

I have installed jitsi meet on ubuntu server successfully. I want to get the participant information into my database ,so how can I do it ?

As I have the external api provided by jitisi meet which i integrated with iframe with my new url where I can able to event listen for join and left participant, is this only way to do or any other way to get event listen when participant join or left meeting ?

If I will use this one then what about mobile applcation event listen ?
