Editing $PROFILE in Azure Cloud Shell

I have setup Azure Cloud Shell, and put my profile script at default $PROFILE location, which appears to be /home/username/.config/PowerShell/Microsoft.PowerShell_profile.ps1

However I noticed that only /home/username/clouddrive is persisted. So after some time, my profile is lost.

How can I have my profile persist, so I don’t have to keep setting it up from time to time?

Or is there a way to make $PROFILE to point to some place in clouddrive and persist that setting?
