How can I access each element in an array and use it for filtering data

Question

I am trying to get an array in my req.query and want to use the elements in that array for filtering of data but unable to do so.

As you can see in the below code I am trying to apply conditional filters in a dynamic set of data. I am passing the views as an array in the req.query in which I want to search documents whose value lies between the first element and the second element of the array.

if someone can please help me to resolve this issue.

Please find below the relevant code

url applied to below get method : 

// http://localhost:3001/userfilterlist/check?views=[20,29]

router.get('/userfilterlist/check' , async (req , res) => {
    //console.log(req.query.views);
  
    let aggrQuery = [
        {
            '$match': {
                $and: [
                    req.query.views ? [{ 'views': { $gte: req.query.views[0], $lte: req.query.views[1] } }] : [],
                ]
            }
        }
    ]
