Hi,

Interesting... not sure why you cannot see.  I was able to access on a PDI associated with my personal email address as well as one work email. So I don't think a limitation there.

After opening PDI, I typed in 'Plugin' in from the 'All' menu search box.  It brings me to the Application Manager.  I search for 'Legal' and it shows me the LSD apps under the ServiceNow Product section. (screenshot attached for reference).  

If you are still not seeing...may be another issue?

Hope this helps.
