XCP-NG iSCSI LUN Expansion

I have added storage to my storage device that is serving XCP-NG storage over iSCSI. I have expanded my lun, but am not able to get XCP-NG to see the expanded storage. There should be a way for me to expand the partition to take up the entire storage space.

I have followed the following steps: https://support.citrix.com/article/CTX120865 with no luck. Have any of you done this successfully?
