Trigger "COLLABORATION.ACCEPTED" doesn't work for new collaboration (Webhook)

Hello,

I tried to use box webhooks to catch a new collaboration acceptation after having created it with box API. I notice that it works perfectly when the account already exists for this new collaboration on a folder. But if the account doesn't exist, there is no trigger on "COLLABORATION.ACCEPTED".

I’m looking for a solution for the webhook to let me know when a user creates his box account and accept the collaboration at the same time.

Thanks a lot.

Christophe
