How to delete an entry in the database by _id?

Question

MongoDB

There is a database of users.

I want to make it so that when you click on the cross, user data is deleted.

<form action="/personalList" method="post">
    <td><input type="hidden" name="id" value="<%= item._id%>"><input type="submit" value="&#10006" ></input></td>
    </form>

When loading from the database, the user's _id is passed to the hidden input and by the button it is returned to the server. Most likely an attempt at data type conversion. Tried many solutions. Perhaps someone knows how to implement the delete function?

UPD Solved the issue.
personal.remove({_id: req.body.id})
change to

personal.remove({_id: req.body.id}, (err, results) => {
  })
