How to fix deprecation warning for Chunk.modulesIterable?

Question

I am the maintainer of external-svg-sprite-loader and I noticed that when using it with webpack 5 I get the following warning:

[DEP_WEBPACK_CHUNK_MODULES_ITERABLE] DeprecationWarning: Chunk.modulesIterable: Use new ChunkGraph API

The build passes but I would like to able to fix this deprecation warning. However, I can't find any documentation about modulesIterable or the ChunkGraph API. Where should I look for it and what would be a potential solution for this issue?

If you want to iterate through modules in chunk, you could do it like this:

compilation.chunks.forEach(chunk => {
  compilation.chunkGraph.getChunkModules(chunk).forEach((module) => {
    // module is available here
  })
});

You could find other useful methods of this class in its source code. If you want to manipulate modules in chunk, probably it's better to use ModuleGraph class. For example:

compilation.chunks.forEach(chunk => {
  compilation.chunkGraph.getChunkModules(chunk).forEach((module) => {
    const exportInfo = compilation.chunkGraph.moduleGraph.getExportInfo(module);
  })
});
