Facet by Relationship and Render Sidebar UUIDs

[aseyedia]

Is your feature request related to a problem? Please describe.

In our custom DSpace configuration, I have a relationship in discovery.xml called isProjectOfConceptSet:

    <bean id="searchFilterIsProjectOfConceptSetRelation" class="org.dspace.discovery.configuration.DiscoverySearchFilterFacet">
        <property name="indexFieldName" value="isProjectOfConceptSet"/>
        <property name="metadataFields">
            <list>
                <value>relation.isProjectOfConceptSet.latestForDiscovery</value>
            </list>
        </property>
        <property name="isOpenByDefault" value="true"/>
        <property name="pageSize" value="10"/>
    </bean>

As you can see, it is aDiscoverySearchFilterFacet that I've placed in the sidebarFacets section of my defaultConfiguration. The behavior I would like is to create a sidebar facet that lists like maybe 5-10 of the highest-hitting Project entries related to Concept Sets, and then the rest are like "load more" or something like that.

However, what is happening is this:

Instead of the dc.title of the Project (this is a customization of the default Project), we are given the UUID of this Project. I understand that Project is distinct from Publication, but we have created a number of Publication-like Entity Types for this instance of DSpace and Project is intended to be one of them; I also had to alter ds-project-search-result-list-element to show dc.description in a Search List because by default, it showed nothing.

Describe the solution you'd like

Like I mentioned before, I would like a list of maybe hyperlinked dc.titles of these Project entries, allowing the user to subset by related Project Item. The functionality is almost there, I just want the UUID to be rendered.

Describe alternatives or workarounds you've considered

Based on an investigation of the DOM, it seems that the lowest-level Angular component that governs the behavior of these little boxes is ds-search-facet-option.

However, exactly how I would go about rendering the UUID is beyond me. I have tried getting the DSO for the UUID using functions dso-redirect.service.ts and then later identifiable-data.service.ts and then extracting the name using dsoNameService.getName(dso), but that doesn't seem to be working.

Additional information

If I could get a pointer in the right direction, I would be happy to try to implement this myself, because as it stands, I'm concerned that I'm too narrowly focused on ds-search-facet-option.
