How to filter List Documents with relationships

I want to filter the document based on reference which is a relationship with other table 'references'. reference field can be nullable

Not supported

Yet

then how can I do that, is there any work around?

I have to only show the guests of the person who is currently logged in

is there any other way? Please there must be something we can do if we can't able to filter the relationships

atleast tell me the how to use OR between multiple queries instead of AND

Not supported yet. You would need to make separate API calls

If you have document security enabled and documents are configured with read access for certain users, people will only be able to fetch what they have read access to
