IPs used by Bubble to connect to Azure

I have a development database in Azure and I succeeded in connecting it to Bubble but in order to do that I had to deactivate the default firewall.
How can I find the range of IPs used for outgoing connections from Bubble, in order to configure my Azure firewall accordingly ?

Could you see them in the logs on Azure?

There’s like between 5 and 10 that you need to include in the firewall. I’ve had to manually iterate thru each time to find which IP was being blocked and add it.
