Unable to increment field in mongodb using mongoose - node.js

Question

I have a document in mongodb. The document in This function is able to find the document and it returns it but I can't for the life of me get this function to update the count field by 1. The current document in mongodb if it helps is:
{
_id: 60c5e4c3fba7edd232cf57e7,
counterName: 'give_me_the_count',
count: 1,
updatedAt: 2021-06-13T11:47:02.575Z
}
The code is returning the original document to updatedCounter. But updatedCounter.count is undefined.
async function updateAndReturnNewCount() {
let doc = await Counter.findOne({ counterName : "give_me_the_count" })
var count = doc.count
let updatedCounter = await Counter.findOneAndUpdate({ counterName : "give_me_the_count" },
{ $inc: {"count" : 1 }},
{ new: true,
useFindAndModify: false },
function(err, doc) {
if (err) { console.log(err)}
else {console.log("success")}
}
);
console.log("updateAndReturnNewCount fired")
return updatedCounter.count
}

Your query is incorrect for the operation you wanted to do.
Try this one:
await Counter.aggregate([
{
$match: {
counterName : "give_me_the_count"
}
},
{
$set: {
"count": {
$add: [ "$count", 1 ] // Increment $count by one
}
}
}
])

Edit:
Usage:
async function updateAndReturnNewCount() {
let doc = await Counter.findOne({ counterName : "give_me_the_count" })
var count = doc.count
let updatedCounter = await Counter.aggregate([
{
$match: {
counterName : "give_me_the_count"
}
},
{
$set: {
"count": {
$add: [ "$count", 1 ] // Increment $count by one
}
}
}
])
console.log("updateAndReturnNewCount fired");
console.log(updatedCounter);
return count++;
}
