Capacitor local plugin support not working

Follow the information here: I have created the default capacitor plugin with the echo method. Inside of the vue file, I have the following:

import { Plugins } from '@capacitor/core';
import 'my-bluetooth-plugin';

async echoDevice() {
	const { MyBluetooth } = Plugins;
	await MyBluetooth.echo({ value: 'test' });

Note: I was unable to run npm link in the plugin folder and then npm link my-bluetooth-plugin and npm install my-bluetooth-plugin as noted here as it simply doesn’t work or do anything. Simon Grimm also ran into the same issue in this video (set to the second he talks about it) and had a workaround of doing npm install ../my-bluetooth-plugin instead. Doing so has caused another error which I believe to be related to the build process:

Module build failed (from ./node_modules/eslint-loader/index.js):
Error: No ESLint configuration found in /Users/username/Projects/my-bluetooth-plugin/dist/esm.

Please help either with the npm link or the eslint issue. I’ll take either at this point!

After 3-4 wasted hours (ugh!), using npm link never ended up working but I was able to get the following to work. I had to run the following within the main project:
npm install ../my-bluetooth-plugin

Then I had to stop the running process and run again as:
npm run serve --preserve-symlinks
