Github actions: Creating releases for multiple branches in a single workflow

I am new to github actions, I have a good idea on how they work but I am having troubles creating releases for multiple branches. Is it possible to create multiple releases from multiple branches in a single workflow?

I currently having working workflow that generates and deploys releases for my main branch. I now want to create releases for a second branch that is slightly similar but has varying functionality.

My problem and my question is:

• How does the github workflow differentiate between the main branch and the other branch to create the releases from the .yml file in the main branch? I know you can use if: github.ref but I am not sure how to go about doing it.
• Should I create a seperate .yml in the second branch, with a separate workflow and create different tag?
• Should I create another entry in my matrix that only relies on the second branch?

Below is my .yml in my main branch:

name: "CI/CD"

on:
  push:
    branches: [ main, example ]
  pull_request:
    branches: [ main, example ]

env:
  QT_VERSION: 5.15.2
