Drizzle Studio and Safari - how to make drizzle-kit studio use self-signed cert?

I'm attempting to use Drizzle Studio in Safari. When opening `local.drizzle.studio`, safari-specific instructions come up, so I followed them and ran the following:
```
brew install mkcert
brew install nss
mkcert -install
```
However, this doesn't seem to do anything. `local.drizzle.studio` is still attempting to call the normal HTTP localhost URL, and it is getting blocked by Safari's policies. Are there additional steps here (creating a cert, getting drizzle studio to use that cert, etc) that are not documented or that I've overlooked?

Thanks.
