    db.collection('screams').doc(req.params.id).doc('users').add(mark)
    .then(doc=>{
        return res.status(200).json({handle: 'data added successfully'})

add() is a method of a CollectionReference, but with

db.collection('screams').doc(req.params.id).doc('users')

you are not defining a CollectionReference, since you call twice the doc() method.

You need to call the collection() method of the DocumentReference defined by db.collection('screams').doc(req.params.id), as follows:

app.post('/screams/:id',(req,res) => {
   const mark ={
       Mark:req.body.Mark,
       Name:req.body.Name
   }
    db.collection('screams').doc(req.params.id).collection('users').add(mark)
    .then(docRef => {
        return res.status(200).json({handle: 'data added successfully'})
    })
})
