If you run xe cd-list, the new ISO hasn't yet been recognized so we'll need to re-scan the storage repository (sr).
[10:25 oasis iso_images]# xe cd-list
uuid ( RO)          : fcadf37b-7fad-4db1-a0c2-b1449b3e76f1
    name-label ( RW): guest-tools.iso


uuid ( RO)          : fdf30c16-4bfe-4e97-83dc-80b7928f8a77
    name-label ( RW): ubuntu-18.04.5-live-server-amd64.iso


uuid ( RO)          : ab17ffe5-0049-4d55-bd93-33b54ef479b8
    name-label ( RW): ubuntu-20.04.2-live-server-amd64.iso

Re-Scan Storage Repository (SR)

First, get the UUID of the relevant ISO storage repository by using xe sr-list. We can filter on type=iso to limit the output.
[10:23 oasis iso_images]# xe sr-list type=iso
uuid ( RO)                : 190d3dff-5801-36aa-887f-3981912f9640
          name-label ( RW): XCP-ng Tools
    name-description ( RW): XCP-ng Tools ISOs
                host ( RO): oasis
                type ( RO): iso
        content-type ( RO): iso


uuid ( RO)                : 0593ee67-b5b0-0861-f20c-e2b1c8d2bc12
          name-label ( RW): ISO Images
    name-description ( RW): 
                host ( RO): oasis
                type ( RO): iso
        content-type ( RO): iso

Then, we'll use the xe sr-scan with the uuid required parameter to rescan and update the new ISO. xe cd-list displays the new results.
[10:32 oasis iso_images]# xe sr-scan uuid=0593ee67-b5b0-0861-f20c-e2b1c8d2bc12
[10:35 oasis iso_images]# xe cd-list
uuid ( RO)          : fcadf37b-7fad-4db1-a0c2-b1449b3e76f1
    name-label ( RW): guest-tools.iso


uuid ( RO)          : e5570fe5-ea6f-4f6c-848f-73300047e8f7
    name-label ( RW): CentOS-Stream-8-x86_64-20210406-boot.iso


uuid ( RO)          : fdf30c16-4bfe-4e97-83dc-80b7928f8a77
    name-label ( RW): ubuntu-18.04.5-live-server-amd64.iso


uuid ( RO)          : ab17ffe5-0049-4d55-bd93-33b54ef479b8
    name-label ( RW): ubuntu-20.04.2-live-server-amd64.iso


[10:35 oasis iso_images]# 

Now, the new ISO will display in the Xen Orchestra UI as a bootable mount for installing a new Virtual Machine with this operating system.
