Your png is in RGB mode so is OK
You can get a simple result using Filters -> Animation -> Blend unfortunately the documents leave a little to be desired
https://docs.gimp.org/2.10/en/script-fu-blend-anim.html
In this it goes from one colour to another so needs 3 sets for RGB red > green : green > blue : blue > red
If you make 3 sets they can be joined by opening as layers.
