Is Google Cloud VPN only compatible with Compute Engine instances?

Use case: I am managing both GCP infrastructure and local infrastructure and am looking for a way for an app on Google App Engine to send data to/from a MySQL database on the local infrastructure, which is behind a VPN. I've set up and tested a Cloud VPN Gateway and VPC Connector that allows a Google Compute Engine instance to connect to the MySQL database and send and retrieve data.
Per this thread, and my own experimentation, the Google App Engine standard environment cannot currently connect to a local network via Google Cloud VPN directly. I've also been testing Cloud Function and Cloud Run to see if they can connect with the Cloud VPN, and it seems that they also have this limitation.
What I'd like to confirm is that only the Google App Engine flex environment OR a Google Compute Engine instance can connect through Cloud VPN. Google's documentation across all these resources doesn't ever outright say whether any of them can connect to Cloud VPN through a VPC Connector (just that they can connect to GCP networks via VPC Connector), so I'm hoping someone here can corroborate my testing. Additionally, is there any other GCP resource that can make use of this functionality that I've missed?

Access Google Cloud SQL - SQL Server from Google Cloud Function

I'm trying to contact a SQL Server hosted on Google Cloud SQL using Private IP and VPC serverless access in Google Cloud Function)
This is actually not working (The Google Cloud Function reach its timeout) but in the same condition I succeed contacting on the private IP a PostgresSQL server, all other things being equaled (the infrastructure is deployed by Terraform to ensure exact same conditions, I just change the database_version)
The database, the VPC Serverless access and the Google Cloud Functions are all deployed in the same region.
Is there any workaround or solution to make it work?
If you check the oficial documentation Connecting to Cloud SQL from Cloud Functions, you will see that there is no support for connecting to SQL Server Beta from Google Cloud Functions.

How to merge google cloud sql and google app engine projects?

Our app engine project uses google cloud sql database. Historically cloud SQL was a separate project, and app engine application had permissions to work with it.
Now Google uses a new google cloud console. We see 2 different projects with different project ids.
How can we merge the cloud SQL and app engine projects?
The DB size is about 25Gb and it is used every second so we can't move it to app engine project.
And we can't add app engine project source to Cloud SQL project, there is no App Engine link in new console.
Thanks
