APP.ZOOM.US does not load on iPad browser

I often use the call centre in zoom's desktop app and webpage, I want to do the same on my iPad, but when opening zoom in chrome, safari on iPad, there is no call centre in it, and when accessing the webpage, the page loads as blank.

Please let me know how can I use the call centre on my iPad say, at the moment I can only use remote desktop to do this.

Thank you very much for any reply
