I can confirm.

Try this.

Right-click on your desktop, goto "New" and choose "shortcut".

In the create shortcut dialog, browser to opera.exe in Opera's install folder. You can find the install folder path by going to the URL opera://about.

Click Next.

Name the shortcut Opera as Chrome and click finish.

Then, right-click on the "Opera as Chrome" shortcut, goto "properties" and edit the target field.

In the target field, after the command to opera.exe, add a space and then:

"--user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Safari/537.36"

so that it looks like:

"C:\Users\yourusername\AppData\Local\Programs\Opera\opera.exe" "--user-agent=Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/125.0.0.0 Safari/537.36"

for example.

Then, click apply and ok out.

Then, with Opera closed, start Opera with that "Opera as Chrome" shortcut and try things out.
