How to store and retrieve checkbox state on refresh of page? Mongoose/EJS/Nodejs/Express

I have a checkbox, essentially like a to do list. When i check the box, I want to retain the state even after i refresh the page by using mongoose. I do know of localstorage, however EJS runs on a server side. Currently I am able to post the checkbox to my express side.

IN EJS

form id="form2" action="/check" method="post"></form>
<input form="form2" type="checkbox" name="checkboxx" onChange="this.form.submit()">

IN EXPRESS

app.post("/check", function(req,res){
  Item.updateOne({checked: req.body.checkboxx.checked}, function(err){
    if(err){
      console.log(err);
    } else console.log("successfully updated db")
  })
  
  res.redirect("/")
})

My collection is "Item", the schema includes a boolean property "checked" checkboxx is the name of the input checkbox. Any way to update the information of the checkbox state and reload the saved states upon refreshing the page?
