Grab user id from url parameters

Thanks to chatdash, I am able to create and deploy a chatbot within an iframe. Is there a way to pass a user_id URL parameter (or possibly other metadata) that can be added to the recordings? This will allow a lot of easy customization.

For, example: https://voiceapp.chatdassh.app/prototype/67919ab9f2ecebe0fe33?user_id=4375

Or, is there another way you would recommend user management for web users?

Thanks,

Praveen
