I found a solution.
#1: Create a powershell script with this content:
Start-Process pwsh.exe -Wait -verb runas
#2: Save the script in a location of your choice
#3: create a shortcut with this command line, replace "C:\Temp\PowerShell 7 admin.ps1" with the location of the script you created
"C:\Program Files\PowerShell\7\pwsh.exe" -ExecutionPolicy Bypass -file "C:\Temp\PowerShell 7 admin.ps1"
