mongoose switch database for specific operations

I have multiple mongodb databases, each database has the same collections and the data has the same structure. I will use mongoose to access / write this data but for this i need to select the database at each opperation.

I tried this, but it's not working (it's still using the DB from the connection string):

mongoose.connection.useDb('myDB')
const data = new DataSchema({test: "Hello"})
data.save()

try this:

const db = mongoose.connection.useDb('myDB')
const data = db.model("Data", DataSchema({test: "Hello"}))
data.save()

Following has worked for me in the past

const db = mongoose.connection.useDb('bucket_db');
const BucketCollection = db.model("Buckets", BucketSchema);
const bucket = await BucketCollection.findOne({ OldId: customer.BucketId });

Basically, you have to tell mongoose to use the Schema with new db you have just connected to
