RLS policy 'in' not working

Hi,

I'm trying to add an RLS policy to allow SELECT operation on a table.
My table looks something like this

room_table:

id (Primary Key) | room_members(array of uid) | room_owner_uid (uid)

id (Primary Key) | room_members(array of uid) | room_owner_uid (uid)

id (Primary Key) | room_members(array of uid) | room_owner_uid (uid)

id (Primary Key) | room_members(array of uid) | room_owner_uid (uid)

where:

In the

USING

USING

expression, I tried to do:

uid() IN room_members

uid() IN room_members

uid() IN room_members

uid() IN room_members
but it doesn't work.

A lot of example provided does not include this type of

USING

USING

expression, so I have not had any luck getting the right way to do this.

Anyone knows how to do this? Thanks!
