'Running Power Platform / Selenium automated tests on build agent gives error "session not created"

We are investigating executing Power Platform automated tests in our Azure DevOps pipeline.

The tests run and pass successfully when we run them from within a Power Platform session.

However, when we run them in a pipeline (meaning they get executed on a Windows Build Agent that we've created) we get the error below.

The framework uses Selenium as part of the test execution stack.

Has anyone else experienced this and resolved it?
