i want take data for chat room beetween two users by subscription
i have schema like this

type User @withSubscription  {
	id: ID! 
	name: String! 
	email: String! 
	messages: [Message] 
}

type Message @withSubscription {
	id: ID! 
	message: String! 
	senderMail: String! @search(by: [hash, regexp, term])
	receiverMail: String! @search(by: [hash, regexp, term])
	timestamp: DateTime! 
	users: [User] 
}

and take data like this

useSubscription(SUBSCRIPTION_QUERY,
        {
            variables: {filter: { senderMail: {in: [senderMail] }, receiverMail: {in: [email]}}},
        }
    );

but it give data only in one way - for sender email Messages only

i need to create new subscription like this

useSubscription(SUBSCRIPTION_QUERY,
        {
            variables: {filter: { senderMail: {in: [email] }, receiverMail: {in: [senderMail]}}},
        }
    );

it gives messages from recieverMail too

but maybe be way to create subscription for both cases

Wrap them in filter: { OR: [{ senderMail: ... }, { receiverMail: ... }]}

Without specifying the logic it defaults to AND
