How to Debug specific user/token using Delve in MUX?

Hello all,
As the topic is much self explanatory, I want to debug a specific user’s session in mux using delve. When we run mux as a service, it runs under user’s account who executes it (i believe).
If postman would trigger any HTTP action with some kind of token in header, I want delve to wake up and start debugging. Is it possible with existing Delve or something needs to get added to delve source code?
Need help, thanks
