Hey I made some updates in ./prefect/config.toml how to reload changes? For example I added slack_web_hook url

Secrets should be loaded into the context when you import Prefect so it should take effect next time you run a Flow

Ok, but how to reload config on prefect server? Right now I'm editing prefect package config and then i do prefect server start. But changes are not pulled from the config

But the secrets are not stored on the Server. You need them on the agents (and local secrets) if using Prefect Server. Only Cloud stores secrets
