I found out what the problem is, the APP in unRaid points to documentation of https://github.com/skibish/ddns/blob/master/README.md
However, the actual container image being used is ronnieroller/ddns, for which the documentation can be found here: https://hub.docker.com/r/ronnieroller/ddns
Example:
token: "AMAZING TOKEN" # Digital Ocean token
domains: # Domains to update
- "example.com"
forceIPV6: true # Use IPv6 address resolve (Default false and force IPv4)
records: # Records of the domains to update
- type: "A" # Record type
name: "www" # Record name
- type: "TXT"
name: "demo"
data: "My IP is {{.IP}} and I am {{.mood}}" # "data" key is optional. You can write here
# what you want and reference values from "params".
# Key "IP" is reserved.
params:
mood: "cool"
notify: # Optional notifiers
smtp:

Is in essence, the App is pointing you towards the wrond documentation.
I managed to get it working.
