Use AOMEI Backupper server on Azure Storage

Hi, Is there any expierienc using Backupper on a Azure Storage drive? It seems that this is somehow not working smoethless. We can create a network drive as usual in Windows. Select this drive in AOMEI Backupper. Then AOMEI requires several times the username and password (what is in this case the name of the storage and an access key. Any expierience with this or is there a way to store the username and password in AOMEI?
