Mongodb – Serialize consumers of SQS fifo queue in node app

I am trying to implement serialization in the consumers of a SQS queue, which runs in multiple nodeJs instances. i.e. what I am trying to do is ensure that stuff is done in the same order they came in, one thing at a time. My initial thoughts were to put in some kind of semaphore mechanism potentially using a lock document in documentDb (mongo), which is the services main repository, by waiting on changes to that document using change stream mechanism. Each instance will have their own identifier and the lock file will contain the id of whoever owns the lock. Not sure if this is the best way to go about doing this, so I am asking, is there a better way to achieve this? Or would this work however with slight modifications? My main concern is instances potentially getting starved which would defeat the purpose of all of this, since one instance might get the lock twice in a row if they are lucky. A sequence counter could also be put in place with each instance keeping track of how far they are in the sequence and when they attempt to grab the lock they could compare their sequence counter with what is on the lock, and will keep waiting if they are behind. Though that seems like it would be pretty fragile and could stall everything if an instance died not completing the sequence step. Any ideas?

Code looks something like this

const LockSchema = new Schema({
  id: String,
  owner: String,
  createdAt: { type: Date, required: true, default: Date.now },
});

LockSchema.index({ createdAt: 1 }, { expireAfterSeconds: 600 });

const Lock = mongoose.model("queue-lock", LockSchema, "locks");


const filter = [{
    $match: {
            { operationType: "delete" }
        }
    }];

const options = { fullDocument: 'updateLookup' };

let lockStream = Lock.watch(filter, options)

lockStream.on('change', event => {
  if (!event.fullDocument) {// deleted
    result = await Lock.findOneAndUpdate(
      { id: "migration-lock" },
      { $setOnInsert: { owner: whoAmI } },
      { upsert: true, new: true }
    ).lean();
    if (result.owner === whoAmI) {
      // proud owner of lock, do stuff
      await Lock.deleteOne({ id: "queue-lock" }); // when done

    } else {
      // keep waiting
    }
  }

});
