Suggestion:
Add comments :
// Only one "?" is needed here. If the sastoken starts with "?", please removing one "?". The sastoken created by azure portal starts with "?". Using it in Code Snippet to create client will fail.
Reason:
SASToken from Azure Cli doesn't start with "?". But in Azure portal, sastoken starts with "?". Current code snippet not work with the later one.

Suggestion:
Add comment:
//you need to authenticate with azure identity and add role assignment "Storage Blob Data Contributor" to do the following operation.
Reason:
The sample will fail if client is constructed with SASToken.
