How to cancel a Subscription properly ?

Hi,

When i'm in the /subscriptions/subscriptions/ i can see all the subscriptions listed, and each one has its own action (three dots) that allow only 'Edit'

When i click Edit it open a page with the specific subscription and there's three options : Active, Cancelled and Pending.

But there's a notification that says : ((To avoid data inconsistency with the remote gateway, editing subscription manually is not recommended, and changes need to be reflected the remote gateway manually.))

if i select cancel and hit update it's not recommanded, so what is the recommanded way please ?

Thanks in advance.
