katalon mobileEmulation view desktop site

Hello,
I’ve been testing Mobile Web Site using Chrome’s mobile Emulation.
Since the chrome version was updated to 90, it now displays desktop sites.
This symptom does not reappear on released production sites.
The event is reproduced on a site where basic authentication is set for developers.
Is there a way to use Chrome’s mobile emulation to view mobile sites?
The log that shows my chromedriver settings is excerpted from Katalon Studio and written below.

I inquired about Chrome Driver below, but it didn’t work.

I pray for help.
Thanks.
