SitemapGenerator does not have the function writeToDisk()

[ametad]

SitemapGenerator does not have the function writeToDisk() yet. Or at least I cannot get this to work...

The classes Sitemap and SitemapIndex does have the implementation of writeToDisk indeed, but not the generator yet. Was this not the plan? Or am I missing something?

The implementation was done here: https://github.com/spatie/laravel-sitemap/pull/283/files

I got confused because of the explanation in the README:

You can also use one of your available filesystem disks to write the sitemap to.
SitemapGenerator::create('https://example.com')->writeToDisk('public', 'sitemap.xml');
