Navigating through yaml files using variables

The title is kind of bad, but I will try my best to explain it.

What I'm trying to do is pretty much navigate through a yaml file as you normally would

var doc = yaml.safeLoad(fs.readFileSync('./settings.yml', 'utf8'));
console.log(doc.admin.permissions);

except I want to be able to do this:

var adminrolename = "admin1";
console.log(doc.adminrolename.permissions);

Is there a way I could do this? I've been looking around and I can't seem to find an answer, I might just be searching for the wrong thing, so sorry if this has an obvious answer

This is what I did for a proof of concept. Remember that keys are case sensitive so doc["admin"] won't be same as doc["Admin"]

Yaml File:

doc:
  admin:
    permissions:
      - abc
      - xyz
  admin1:
    permissions:
      - abc1
      - xyz1

JS File:

const yaml = require('js-yaml');
const fs = require('fs');
try {
    const config = yaml.safeLoad(fs.readFileSync('test.yml', 'utf8'));
    const doc = config.doc;
    console.log(doc["admin"].permissions);
    console.log(doc["admin1"].permissions);
} catch (e) {
    console.log(e);
}

Result:

[ 'abc', 'xyz' ]
[ 'abc1', 'xyz1' ]

Sorry everyone for the inconvenience, @Kinaan Khan Sherwani was right, I did try it, but I messed up the yaml file.

doc[adminrolename].permissions

That is what the correct code is

I didn't put any quotes around the sections... facepalms. Here's what the original YAML was:

This is what I changed the YAML to, to fix my problem:
