Query/Question
I want to use images between tenants using shared image galleries, as described in here using the java sdk, both there is no documentation as to how authentication to 2 different tenants can be done.

Why is this not a Bug or a feature Request?
This can be done using the azure cli, and rest api. I already have a shared image created and the app registration setup, I'm missing on how to deploy the image to a different tenant. These are the steps using the cli:

az account clear
az login --service-principal -u '<app ID>' -p '<Secret>' --tenant '<tenant 1 ID>'
az account get-access-token

az login --service-principal -u '<app ID>' -p '<Secret>' --tenant '<tenant 2 ID>'
az account get-access-token

az vm create \
  --resource-group myResourceGroup \
  --name myVM \
  --image "/subscriptions/<Tenant 1 subscription>/resourceGroups/<Resource group>/providers/Microsoft.Compute/galleries/<Gallery>/images/<Image definition>/versions/<version>" \
  --admin-username azureuser \
  --generate-ssh-keys

Setup (please complete the following information if applicable):

• OS: ubuntu
• IDE : intelliJ
• Version of the Library used : 1.22.0
