Hi @JosephSmith278,
At most schools/institutions, integrating with third party apps is something your local Canvas team (usually in the eLearning / IT / Digital Education areas) would assist with or do for you. You could also contact your Pearson rep to get the specific install instructions for their app, but in all likelihood it's not something you'd be able to install on your own if it's a modern integration.
I hope this info helps, even though I know it's not an exact answer. It's the best we can really provide in the community here.
