Deleting entries from array in different documents ids using mongoose [duplicate]

Question

I have a project Schema like this

const projectSchema = new mongoose.Schema({
 name: {
type: String,
required: true,
minlength: 2,
maxlength: 50
},
box: { 
type: [String],
required: false,
minlength: 0,
maxlength: 255
},

isActive: Boolean
});

And I need to delete the entry of olibox from different documents

For example:

If I have 4 different projectSchema IDs and I want to delete 2 specific olibox IDs from these 4 projectSchemas..how can i dot that?

For one single document I am doing like this to delete one array element..

project= await Project.findByIdAndUpdate(req.project._id,{$pull :  {'box': req.params.oliId}},{new :true});


console.log("In post");

Can I use $in with it somehow?

Try and see if this works. I am hoping it does.

Project.updateMany(
  {
    _id: { $in: ['xxxxxxxxxxxxxxxxxxxxxxx', 'xxxxxxxxxxxxxxxxxxxxxxx'] }
  },
  { $pull: { box: { $in: [8025, 7323] } } }
);
