Wanting to have a app integrating Waiver forever with Nextcloud

I really need this integration if anyone can take on this challenge. I’m surprised it hasn’t been done yet.
Waiverforever already connects to Dropbox to Google and many others even zaiper.
So this should be easily done.
Anyone can help or where do I put in a request to NEXTcloud.

I do not know Waiverforever. But maybe you can use WebDAV.
