Postgres function not returning any rows but no errors

I have this below function which returns no rows, but no errors as well. Am I missing any statement over here to return the rows?. If I execute the select statement alone I do get results.

CREATE OR REPLACE FUNCTION public.create_new_conversation()  RETURNS TABLE(chat_id text, members jsonb)  LANGUAGE plpgsql AS $  function$   declare    the_record record; begin    select conversation_id, participants    into the_record    from public.conversations    where conversation_id='123456';     --    return conversationid; end; $  function$
