I’d start here.
I’m not running selinium, but our browser testing has 2 tricky parts worth keeping in mind,
Start a local server as background task, and wait on it to be serving (all of this can be skipped if you’re testing against a cloud environment)

        - run:
            name: Start
            command: << yourCommandHere >>
            background: true
        - run:
            name: Wait-on <<parameters.wait-on>>
            command: npx wait-on <<parameters.wait-on>>

Then trigger your tests.
