Defender webfilter: Blocking legitimate urls

We have two URLs:  live-lia-pushy-service-v2.euw1.prod.hosted.lithcloud.com and live-lia-pushy-service-v2.euw1.stage.hosted.lithcloud.com getting blocked by windows defender web filter. These are completely safe and legitimate URLs responsible for providing important services to our website. How do I submit these URLs for re-evaluation so that they can be whitelisted at a global level for our customers?

I have attached the screenshot of the error message.
