-# 2020-05-23: As of 2020-05-04, Slack is blocking TLS connections using TLS v1.1 or lower.
-# This was causing Invoke-WebRequest to error out with a 404 / WebCmdletWebResponseException error.
-# This may only affect systems with certain version of .NET (which is what Invoke-WebRequest relies on under the hood), due to it affecting the system's default TLS version.
-# But the line below should force TLS v1.2 to be preferred.
-# A better solution would be to change the system default TLS version to something higher than v1.1.
