Selecting other branch instead of master as a source repository on AWS CodeBuild

Question

How to specify different branch instead of master branch on AWS code deploy while using Github as a source provider? I see there is no option to select in the console to select a branch(maybe I missed).

I tried to checkout to different branch while we are in the pre_build phase, but it failed in the Download Source phase itself as the master branch doesn't have YAML file.

version: 0.1

phases:

  install:

    commands:

      - apt-get update -y

  pre_build:

    commands:

      - git checkout testbranch

You can specify the branch in the "source version" field when you start a build. It will accept anything that "git checkout" accepts: commit ID, branch, tag, etc.
