How not to notify a user when the task is cancel

Question

Hi,
I have this workflow in GP,
Apply Timeoff --> Recommend Timeoff --> Approved Timeoff
Where Applicant can apply for Timeoff (via ApplyTimeoff block), RecommendingOfficer can "Recommend" or "Reject" timeoff (via the RecommendTimeoff block), and finally the Approving Officer can "Approved" or "Reject" the recommendation (via the ApprovedTimeoff block)
The GP is configured in such that the ApplyTimeOff block have successful result state Target to RecommendTimeoff block. In the RecommendTimeoff block, it has the successful result state, targets to the ApprovedTimeoff block whereas the unsuccessful result state target to Terminate. Likewise for the ApprovedTimeoff block, it has both the successful and unsuccessful result state target to Terminate.
Those roles are in GP and they are map to the EP Group respectively. And in each group, there are EP users tag to it.
During Application of the ApplyTimeoff, I have a drop down list of RecommendingOfficer which I can select in WD UI. And Once I selected the particular person from the list, the request will route to the RecommendingOfficer as a pending task in the GP Runtime. From here, that selected person from that Recommending Officer can "Recommend" or "Reject" the request.
When that person from the RecommendingOfficer approved, the request will route again and this time to the Approving Officer.
However, when the reject the request, the task will also be route to the Approving officer.
How do I configured in such as way that when the recommending Officer reject, it request will not be route to the Approving Officer as a pending task?
can help? Thank you.
thank you.

Let occasional users log in as guests
A guest user account lets others use your Mac without setting up a full account or using someone else’s. You can use parental controls to limit guests’ activities, and specify which folders they can view.   [by default, they cannot see any other users' files]
In Users & Groups preferences, select Guest User in the list of accounts.
Select “Allow guests to log in to this computer.”
If you like, select “Enable parental controls,” then click Open Parental Controls. For details about the limits you can set, see:Set up parental controls
To let guests use your shared folders from another computer on the network, select “Allow guests to connect to shared folders.”
When guests log in, they don’t need a password.
... and anything created while logged in as Guest is deleted when you log out.
