max concurrency is to 7 and right now, 5 workers are started but at any time, only one 1 worker is actively running

script moves to next worker only after the current worker is finished.

I expected the script would run 7 workers and wait for any of the workers to finish to start the next so effectively, utilizing all 7 browser contexts
I expected the script would move to the next worker only if there is a available spot in concurrency

You are using cluster.execute which waits for the task to finish. You want to use cluster.queue instead.
