This doesn't affect the parsing, but the default value for the "vis" parameter should be an object and not an empty array. Line 468 in -> explore-assistant-extension/src/hooks/useSendVertexMessage.ts

The only other that would be important to include in the parser is support for the dynamic_fields param of the url (ie. supporting custom dims, measures and table calculations)
