Dell drivers not showing as 'required' after importing Dell Third-Party Software Update Catalog into Configuration Manager

I have imported the Dell 3rd Party Catalog into Configuration Manager according to instructions

Dell Business Client Update Catalog for Microsoft EMCM and SCCM

successfully imported, subscribed and selected the categories I need

Dell drivers are showing in the Software Update Catalog

But critically, no information for which drivers are 'missing' from devices

I only see one item which is seen as required on all devices

Dell OpenManage Inventory Agent(for Dell Business Client Systems), 5.1.0.4

The item is metadata only, nothing that can be download and deployed

I see Dell System Inventory Agent (DSIAPC_1.4.2.2.msi) is also available as an MSI

Dell System Inventory Agent | Driver Details | Dell UK

seems related, but no sure

Can anyone advise why none of the other drivers in the configuration manager software update catalog are showing as missing? whats other steps are needed, links to relevant documentation appreciated
