A static IP is a must-have feature when dealing with certain services.
In the past, we could use Serverless VPC Access connectors, but this required renting a virtual machine (VM), which contradicts the principles of serverless architecture and significantly increases costs.
Recently, a new method called Direct VPC has emerged, which eliminates the need for connectors. This means it is truly serverless, even when using a static IP.
Currently, Direct VPC can be configured by revision in the Google Cloud Console. However, I would like to enable Direct VPC in Firebase Functions as an option, like so:

vpcConnector: 'test-connector',
vpcConnectorEgressSettings: 'PRIVATE_RANGES_ONLY'
