How to use `OR` operator in Query?

i'm working on a chat functionality. so in all chat applications, we see a chats list on the left that shows with whom you're chatting or have chatted with. either you're the receiver or the sender, it shows the chat item. so to get a list like this, we need to pass a query where the sender_id or the recipient_id is equal to the current user id.
we can do an OR operation for a value of any attribute by passing an array in the 2nd argument of the equal method. but what i need here is something like an OR operation for the name of the attributes and i can't find a way to do that. am i missing something?

my goal above could be achieved by the below SQL

SELECT * FROM chats
    WHERE (sender = {currentUser.$id} OR recipient = {currentUser.$id}) ORDER BY timestamp

in case it helps

This is not supported at the moment. See https://github.com/appwrite/appwrite/issues/2740
