I have implemented a leaderboard using firebase firestore and functions. I want to cache the output of the function and serve applications using this function through cache. Let’s say I cache it for 3 hours. Is there a method to achieve this on firebase using callable functions? and My app is built with flutter.

exports.getScores = functions
    .runWith({
        enforceAppCheck: true, // Reject requests with missing or invalid App Check tokens.
    })
    .https.onCall(async (data, context) => {
        console.log('enforceAppCheck');
        try {
            const scoreQ = await admin.firestore().collection("players")
                .orderBy("score", "desc")
                .limit(7)
                .get();

            return scoreQ.docs.map((doc) => {
                return {
                    player: doc.id,
                    score: doc.data().score,
                    mates: doc.data().checkmates,
                    kos: doc.data().knockouts,
                    level: doc.data().level,
                };
            });

        } catch (e) {
            functions.logger.log("error occured", e);
            return (e);
        }
    });
