Enhance Subi API webhook trigger

. I am currently testing Subi to see if I can synchronize Shopify+Subi with my database and processes. The logic of both Shopify and Subi seems to be to trigger webhooks on specific events. For example, "subscription_contracts/create" on the creation of a subscription. I know how to do it with Shopify webhooks ("orders/create" for example), but not with those of Subi. I had Shopify Support verify that the topics "SUBSCRIPTION_CONTRACTS_CREATE", "SUBSCRIPTION_CONTRACTS_CANCEL", "SUBSCRIPTION_BILLING_ATTEMPTS_SUCCESS", "SUBSCRIPTION_BILLING_ATTEMPTS_FAILURE" indeed had associated webhooks. But they do not trigger when I manage subscriptions.
