Javascript – Prevent window refresh when use focus

I have to implement the next requirement: From a specified page I have to open a new page (new browser tab, lets call it Live tab) and focus on it. Only one Live tab can be opened at a time

What I’ve tried is

const win = this.window.open(url, 'New tab');
win?.focus();

This is working as expected but if the Live tab is already opened, the focus operation triggers a refresh of the Live tab every time.

Can we prevent this somehow ?
