Hey @dguihal Thanks for good work. To continue with this, can you assist us in:

1. Adding further test cases to validate all introduced parameters for UptimeRobot.
2. Generate an updated CRD reflecting the new types introduced. This will help us have a quick glance on updated CRD and new changes.
   2.1 make generate manifests command can support you on point 2.
