I am trying to use the sample labeling tool to create a custom model for the Azure Form Recognizer.
I created a blob container for the sample images. Now, as far as I understood, I need to create a new connection to the blob container from the sample labeling tool, and for that I need a SAS URI.
I am trying to create a SAS URI in the Azure portal, but I don't know what to enter in the allowed IP addresses field.

I don't know the IP address of the sample labeling tool, and it could change, right? What do I need to do to use the sample labeling tool?
