When I use mongoose.connection, models are connected directly with the unique connection. In this case db1 is only used for quering (not model require). But db2 use 2 models. ¿How Can I connect those models with db2 only?

Thanks for helping

const db1 = mongoose.createConnection("atlasuri").asPromise()
const db2 = mongoose.createConnection("localuri").asPromise()

app.get("/",async(req,res)=>{
    const finded =  (await db1).collection("users")
    await finded.forEach(el=> console.log(el))
    res.json(finded)
})

Models

const Criterion1=new mongoose.model('Criterion',new mongoose.Schema({
 name:string
}));
const User=new mongoose.model('Criterion',new mongoose.Schema({
 name:string
}));
