Chrome User Switching Shortcuts

With Windows, you can switch users using Ctrl+Shift+M.

Chrome Keyboard Shortcuts - Google Chrome Help

Windows: %USERPROFILE%\AppData\Local\Google\Chrome\User Data\
Mac: /Users/(Login ID)/Library/Application Support/Google/Chrome

The above directory contains user profile directories such as Profile1.
You can specify them with the --profile-directory option.

>chrome.exe --profile-directory="Default"
>chrome.exe --profile-directory="Profile1"

Also, I think you can deploy some kind of application launcher and launch it.

If you are using Windows, in terms of using Chrome to switch between multiple users, will the user name " be displayed once you switch users and open the settings in the user's window?
If you click on this part, there will be an on/off item for "View Desktop Shortcuts" in addition to editing user names and icons, so if you turn it on, the shortcut will appear on the desktop.("Username" - Chrome)

This will be created as a new link on the desktop, but if you pin it to the start, it will be treated as "pinned the shortcut on the desktop", so if you want to copy it to %APPDATA%\Microsoft\Windows\Start Menu\Programs or less... on the taskbar.
If you just need to leave the icon on your desktop, simply "View Desktop Shortcuts."
