Hi prefect devs, is there a way to use a custom made Secrets provider (as explained in docs)  or the recent 

AWSSecretsManager

 in 

prefect.task

 library tasks? I don't figure out how to force 

slack_notifier

 task to use that Secret provider. for example this code throws an error because Slack try to load PrefectSecrets before Flow init:

Hi @Sebastián Tabares - the

slack_notifier

task isn't configurable for this but most of the tasks in the task library can be subclassed to allow using any parameters you'd like (the

slack_notifier

isn't part of the task library).
