What is the current behavior?
Buffer is not found when using aws-appsync-auth-link pacakge with React Native.

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem.
include the aws-appsync-auth-link package to a react-native project. Use it to implement Apollo v3 with Appsync.

What is the expected behavior?
Buffer package to be included in the aws-appsync-auth-link pacakge dependencies

Which versions and which environment (browser, react-native, nodejs) / OS are affected by this issue? Did this work in previous versions?
React-Native: 0.66
aws-appsync-auth-link: 3.0.7

I was following the instructions on how to create an Appsync link for Apollo v3 and I notice that the signer.ts has this line at the top.

global.Buffer = global.Buffer || require('buffer').Buffer; // Required for aws sigv4 signing

require("buffer") will fail unless you manually install the buffer package your self since it is not included in the aws-appsync-auth-link dependencies.

Was not sure if I should create a issue for this but feel that if signer.ts file tries to require it, it should be included in the dependencies.

I am using yarn with pnp.
For me the issue was resolved by declaring the missing dependencies.
