In this video we will fix the bug.
Belong to the same method.
Okay, right here in preview.
I already got a bit for you.
We need to file the message if it already seen.
If it not seen, we need to handle right?
And from right now we need to change a little bit.
Firstly we will got the user right and we need to view the file one and update.
We will file by the ID over here okay.
By the message adding over here.
And we need to add to set operator and put the user back to the symbol okay.
Because right now we we want to ensure it no duplicate right here.
It also ensure it not duplicate but it not good for the parallel okay.
When we send the two two API at the same time okay we will got the some issue with this approach.
Okay.
We will got some recognition with this approach for one reason.
We need to change this behavior into the update.
Sorry into the atomic operator will be the file file one and update.
Okay.
Please hold here and make sure we return the new update document and also populate if you want.
Right.
And also we need to find the message over here.
Check the message.
And right now what we want to do right now is we need to check if the user just received by okay.
And if the user already inside the scene by we need to skip that.
We will not do anything.
Okay.
So it means if the user already inside the scene by.
Okay.
For example I, I already seen we will not do anything okay.
So make sure you know bit about us.
And right now you need to jump form a little line user.
Thus for the.
