To integrate git pull requests with any LookML projects, you will need to add to the allowlist the range of IP addresses from which your Git provider makes outbound requests.
For github we'll use the IPs listed under "hooks" here: https://api.github.com/meta
In the allowlist settings, we should use "both" for the type setting (both UI and API).
