documentation for build processes hook required

[MikiDev-404]

https://docs.cocos.com/creator/3.8/manual/en/editor/publish/custom-build-plugin.html#custom-texture-compression-processing
so i checked the manual from this link to make cocos 3.0 compress avif format images, but i cant find a single related explaination from the official API documantation that explains how the hooks work and what funtion does that cover (e.g. IConfigs, IBuildPlugin, onAfterBuild and etc.)
