Resizing Browser Windows

Windows 10 ver. 22H2

I have dual monitors and I use Google Chrome as my primary browser.

Often I have two different Chrome sessions running; one on each monitor. It used to be that I could change the screen view using the CTRL key and the mouse wheel. I can still do that, but when I enlarge the view on one monitor, the second monitor follows suit and resizes as well. I would like to be able to resize them independently so that when I resize the view on one monitor, the second monitor stays the way it is.

How do I make that happen? Or CAN I make that happen?

Not having any details in My Computer it will be difficult to guess what the setup is such as how the monitors are connected, whether using 2 video/graphics adapters or just a splitter.

Each monitor is connected to a separate HDMI port on the PC.

I don't think everyone understands what I am getting at.

I open Chrome on Monitor 1. I go to a web page; we'll say Facebook.

Then I right-click the Chrome icon in the Task Bar and select "New Window."

The new window opens and I move the new window over to Monitor 2.

On Monitor 2 I open YouTube.

Then I go back to Facebook on Monitor 1 and when I do a CTRL-Mouse Wheel to zoom Facebook in or out, the YouTube on Monitor 2 with YouTube also zooms in or out.

What I want it to do is, if I do a CTRL-Mouse Wheel to zoom in or out on Monitor 1, I do not want Monitor 2 to change and to stay at the current zoom level.
