Not working on Discord, Twitter, Behance and others :c

I work with customer service. I leave the Opera GX browser open for 8 hours straight with several tabs on my social networks.

Objective: I leave the tabs open, so when a customer chat me I get the notification instantly to answer my customer quickly.
What really happens: If I stay for about 30 minutes outside that tab it is no longer loaded. When I click on the tab after a while it loads, so it is inactive if I don't have it open.

How do I solve this? I want Opera not to inactivate the tabs even if the tab is not open after a long period of time.
I’ve already turned off energy saving mode and everything,
and I can't solve this.

Dont work for me, i need to use more than one account in the same social media

I am trying to access the outlook website (to see my emails) and cannot access it, this error appears. I have 3 Opera GX installed on my computer and the other 2 are running Outlook perfectly, only one of them is giving this error. I already cleaned the cookies and nothing worked.
