Shortcut for Microsoft Outlook

Hi everyone,

I have an issue about creating shortcut for Microsoft Outlook. I am using Macbook Pro with Big Sur.

I want to press Command+1 and go to top of mailbox list.

I created shortcut for Mail app like Mail > Mailbox List > Go to Top

It works for Mail app but I am unable to make it on Microsoft Outlook.

Please help me how to scroll to top of Mailbox list via shortcut on Microsoft Outlook?
