Hello DrgStr,
Welcome to the MS Q&A forum.
Could you please elaborate if your end goal is to create and share dashboard or just get the specific Resource URL?
If you need to navigate to the specific RG in the Azure Portal, you should use the
'https://portal.azure.com/#@TENANTNAME/resource/subscriptions/(subscriptionID)/resourceGroups/(RGName)/overview' format.
Hope above answers your question and concern. Let me know if you need additional assistance. If the answer was helpful, please accept it and complete the quality survey so that others can find a solution.
Sincerely,
Olga Os.
