I can see that you can specify that a free membership is to be set to Pending until manually reviewed and then changed to Active.
Is it possible to create a membership plan with a fee, that once purchased has a status of "Pending" until the application is reviewed?
Unfortunately, that feature is not supported. Currently, as soon as users pay for the subscription, his subscription status will be Active automatically
The system does not support approving subscription (paid subscriptions) at the moment
