Document how to find DOI for funding source

The example codemeta file references the funding agency using a DOI identifier.

"funder":[
    {
      "@type": "Organization",
      "name": "ESCAPE: European Science Cluster of Astronomy & Particle physics ESFRI research infrastructures",
      "funder": {
        "@type": "Organization",
        "@id": "https://doi.org/10.13039/501100000780",
        "name": "European Commission"
      }
    }
  ],

Is there a howto guide that explains how to find the DOI for a funder ?

Using a process of reverse engineering from the DOI in the example I found the registry of well known funding sources .

I couldn't find an easy way to search the registry, so I ended up going to their GitLab repository and doing a text search of the RDF file for the name of my funder.

Yay for OpenSource, but I'm sure there must be a better way of doing this ?
