How to disable background throttling on MS edge

Question

Greetings

We have Cisco contact center solution(UCCE), the agents use MS edge browser to sign in to the agent portal(finesse) where they receive customers calls and answer it.

The problem is that when the agent minimize the browser or switch to another tab, MS edge throttle the connection with finesse server causing the system to forcibly logout the agent after random period of time. This behavior only happens with MS edge browser.

We tried to add finesse URL to the background exception list to disable the throttling feature but the problem is still on going. Is there anything else we need to do/consider in this regard?

Appreciate your support!

MS edge version: 135.0.3179.73
