How to access Jitsi Lib with external Script such us : native javascript, jquery, angular, vue and more

Hello Everyone

It’s nice software jitsi, we glad to use this open source program

i need to communicate jitsi lib with external javascript library such as notive javascript, jquery, angular, vue and more

without to change app build.js instead

it’s really easier with external javascript library to manage new feature enhancement without modify core system in app build

new feature such as : new additional field column, birth date, gender except name

and also add feature to save to database using REST API with external library or else without modify core system in app build

thank you
