Chall-Manager cannot be used on imported CTFd configuration

[NicoFgrx]

Context

If I export the configuration of a CTFd A, configured with a Chall-Manager B.
And I use this export on a CTFd C, configured with a Chall-Manager D.

Issue

The CTFd C will have all configured challenges, scenarios and all CTFd attributes (submission, ....).
But the Chall-Manager D will NOT have the required challenge/scenario to use the new instance easily "plug and play".
This is because scenarios are uploaded while executing the create method of the class DynamicIaCChallenge.

What can we do ?

1. The "hard" workaround: delete and (re)create all dynamic_iac type challenges.
2. Create a new feature in order to : Manually update all dynamic_iac challenges and if they are not exsits in the Chall-Managerr API, create them with the data stored in CTFd.
3. Create a new feature "Import existing challenge to configured Chall-Manager API"
