How to create a Firebase preview URL and associated Github comment?

[BenJackGill]

Can I use this in a similar manner to the other Github Action from the Firebase docs?

Here is a summary of what it does:

• Creates a new preview channel (and its associated preview URL) for every PR on your GitHub repository.
• Adds a comment to the PR with the preview URL so that you and each reviewer can view and test the PR's changes in a "preview" version of your app.
• Updates the preview URL with changes from each commit by automatically deploying to the associated preview channel. The URL doesn't change with each new commit.
• (Optional) Deploys the current state of your GitHub repo to your live channel when the PR is merged.

I was hoping to use this instead of that other action because I also want to update Firebase Functions (the other action is limited to Firebase Hosting only). But I'm new to Github Actions and struggling to figure out how to replicate the original functionality before I even add the Firebase Functions part.
