What does "show" mean?

Under Add cmd it says "Add a new banner and immediately show it." which indicates that "show" means "make this banner definition the active one".

Under Show cmd it says "Show details for a banner." which could mean

"display the properties for one specific banner definition, whether or not it is active"
or it could mean

"make this specific banner definition the active one"
I tried to use Show cmd to change the active banner back to a prior banner definition (which is shown by the List cmd)

az devops admin banner show --id '' --org https://dev.azure.com/MyOrg/
but this didn't work, the current banner remained the active one and the old banner was not activated.

This is replacement of issues : Azure/azure-cli#11047 and Azure/azure-cli-extensions#1056
