hi i have a code for submitting a form to database and i am using express.js in that when submitting the form it works well but when i click on the refresh page or F5 the for is re-submitted i need to know how can i solve this issue
1-controller method

static create = async(req,res,next)=>{
       try{
           let {firstName,lastname,email,phone,username,password,comments,status} = req.body
           let user = new Users(firstName,lastname,email,phone,username,password,comments,'inactive');
           let [created_user,_] = await user.createUser();
           if(created_user){
               let insertedID = await created_user.insertId
               let [users_info,__] =  await user.addUsersInfo(insertedID)
               res.render('createuser',{title:'Create User', message:`user created with id : ${insertedID}`})
           }
       }catch(err){
           next(err)
       }
   }

2-Form

<form class="" action="/users/redirict" method="post" >
    <div class="user-insert-rows">
        <div class="form-floating mb-3">
            <input type="text" class="form-control" id="first-name" name="firstName" placeholder="first name">
            <label for="first-name">First Name</label>
          </div>
          <div class="form-floating">
            <input type="text" class="form-control" id="last-name" name="lastname" placeholder="last name">
            <label for="last-name">Last Name</label>
          </div>
    </div>

3-Routers

userRouter.get('/index',newuserController.index)
userRouter.post('/redirict',newuserController.redirict)
userRouter.post('/create',newuserController.create)

What I have tried:

i tried the router by all ways

userRouter.get('/create',newuserController.index)
userRouter.post('/create',newuserController.create)

and at the for action i used

<form class="" action="/users/create" method="post" ></form>
