access eleventyConfig plugin property

^{Originally posted by btrem February 7, 2024} I have several plugins in my site setup, which are listed in the eleventyConfig in a plugins array (shortened for ease of reading):

plugins: [
    {
      plugin: [AsyncFunction (anonymous)],
      options: undefined,
      pluginNamespace: ''
    },
    {
      plugin: [Function (anonymous)],
      options: undefined,
      pluginNamespace: ''
    }
  ]

One of my plugins has a pluginConfig that I can access via eleventyConfig.plugins[1].options.foo. Can I find this particular property directly? I.e., is there a way to access the plugin via it's name in the .eleventy.js addPlugin directive? I tried JSON.stringify(eleventyConfig.plugins["myPlugin"]) and got undefined.
