Google Compute Engine Firewall Rule To Restrict Traffic O Certain Ports To Specific IP Addresses

I'm trying to restrict port access to certain IP addresses on Google Compute Engine. You are instructed to give ranges, but there are not examples shown how to limit access to just 3 IP addresses that are not in a range.

So for example, lets say I only want to allow these three ips:

22.22.22.22
44.44.44.44
77.77.77.77

How would I format my rule under the form field labeled SOURCE IP RANGES? Below are some things I tried but got errors on:

22.22.22.22,44.44.44.44,77.77.77.77

I tried with a range like this one, but it gave invalid address range

22.22.22.22/24,44.44.44.44/100,77.77.77.77/50

They're specified as CIDR addresses, meaning this:

22.22.22.22/32,44.44.44.44/32,77.77.77.77/32
