Missing BES Support site in WebUI

Running BigFix v10.0.4, webUI Custom site v33 (08 dec 2021).
When a Non-MO user logs in and attempts to view ‘BES Support’ site content (bigfix client upgrade fixlets), they go to the Apps tab > Content > but under Fixlet Collections, they only see “Patching Support”, not “BES Support”:

They have Reader access to the BES Support site in the Console. They can get to https://webui/content/tasks/1 and see the BES Support content directly. Why doesn’t BES Support site show up for them under the Apps > Content page?
