Client query to get possible releasever values from Satellite

When selecting "Content -> Sync Status" in our organization's Red Hat Satellite, under the product "Red Hat Enterprise Linux for x86_64" I can see that repositories have been enabled for the following product versions: 8, 8.1, 8.2, 8.4, 8.5, and 8.6. These correspond to the possible "$releasever" values that a user might have installed on their system, and which appear in their yum configuration files. From a client system, how can I discover this list of values from the Satellite? I would also like to do it independent of the platform of the client; for example, knowing that "Red Hat Enterprise Linux 9 for Power, little endian" exists how can I discover from a x86_64 client that our Satellite has repositories enabled for this product and what their "$releasever" values are?
