Add pool id (poolKey) in Position entity

[lehoangnam040]

Hi,

Is this possible to add poolId as a field of Position entity. When I got the position id -> i wanna know the data of position and data of the pool that this position minted. But with current code seems like I can't

v4-subgraph/schema.graphql

Lines 416 to 433 in d987ffc

	type Position @entity {
	# tokenId
	id: ID!
	# tokenId
	tokenId: BigInt!
	# address of current owner
	owner: String!
	# the EOA that minted the position
	origin: String!
	# created time
	createdAtTimestamp: BigInt!
	# subscribe events
	subscriptions: [Subscribe!]! @derivedFrom(field: "position")
	# unsubscription events
	unsubscriptions: [Unsubscribe!]! @derivedFrom(field: "position")
	# transfer events
	transfers: [Transfer!]! @derivedFrom(field: "position")
	}
