Stream Webhooks IP


I am trying to setup webhooks to notify my backend that videos uploaded to Stream are ready to stream (according to this documentation page Use webhooks · Cloudflare Stream docs )
My backend is behind firewall that restricts IP addresses that can send requests to it.

Is there a pool or a range of IP addresses that I can add to firewall exceptions so that my backend will receive the webhooks from Cloudflare?

I have found those two links:

Adding IPs listed in there to the allowlist worked for me.
