Ip camera and Onvif protocol - My cloud ex2 ultra

Hello everybody

I bought an ip camera (wanswiew W6) which has the onvif protocol.
I have read that it is possible to save the recordings on my mycloud ex2ultra.
can someone give me directions?
I have read that there is a milestone app for this function but I cannot find it.

thank you

The Milestone Arcus app hasn’t been available for download since 2018.
