Question How to use Keyframe Recording on Custom Inspector fields

Hello everybody,

First of all sorry if this should've been in the Scripting Forum, I don't know which one fits the best.

I am currently working on a project where, for a hitbox creator script, I am using a Custom Inspector (or is it considered a Custom Editor?) for the first time.
In this project I'll also animate a lot of this Script's values using Animations... and here is a problem.

While the Animations are only able to place keyframes on the Script's variables and not the Custom Inspector's variables, I figured that the Keyframe Recording Mode would work since all the Custom Inspector does is to allow for a better handling of the behind-the-scenes variables. It still modifies their values as if it was a regular inspector, but in a more intuitive way overall.
So I thought that the Keyframe Recording Mode would detect that the values change and record them, even if through a Custom Inspector.

But when using the Keyframe Recording Mode, none of what I did to the Custom Inspector ever placed a keyframe, or modified an existing keyframe's values for that matter.
The only way to do so was to edit the values in the Default Inspector (which should be hidden, that's the purpose of my custom one) or in the Animation Window directly (which defeats the purpose of the Keyframe Recording Mode).

Even weirder: when I changed the values in the Custom Editor and waited a bit (1-2 seconds), the numerical values within the Animation Window changed. But when changing frames and returning to the one which should have changed, it returned to the previous value, as if it was a visual change which was not saved in the animation.

I tried searching for similar problems but I don't have any idea of the exact terminology I should use so I didn't find anything related.

Is there any way to allow for some CustomInspector-KeyframeRecording interaction or am I forced to rethink my workflow?

Thank you in advance for any answer!



Some code extracts & screenshots for context:

I made visible both the Default Inspector and my Custom One just below.


And here is the Custom Inspector part of this script's code (probably not clean sorry in advance)

Code (CSharp):

2. [CustomEditor(typeof(LocalAttackHitboxCreator))]
3. public class LocalAttackHitboxCreatorEditor : Editor
