Custom reconfigure on cloud plugin

[#1]

Hello,
we are developing a custom cloud plugin.
We would like to be able to change the instance service plan using the “Reconfigure” action on the managed instance, so we have written a method that should override either resizeServer or resizeWorkload (we are not yet sure which one is the correct one).
The issue is that the method is not being called, even though we can see in the logs that a resize action is being triggered.

We would therefore like to ask:

• How does the Reconfigure functionality work?
• Which methods are called in sequence?
• Which interface do we need to implement to override the default method and achieve our desired behavior?
• Are there any mandatory parameters in the involved objects, whose absence would cause the process to fail (even before our overridden method is called)?
