Stopwatch from Shortcuts app

I’d like to create a Shortcut to log swimming lap times for my son.

however, I cannot switch to the Stopwatch functionality from Shortcuts.

Ideally, I would say, “log swim”, and the Shortcuts app would open Stpwatch, and once I switch back to Shortcuts, it would have the recorded Time as input for the next step.

Any ideas? Thanks.

Daud.
