How do I record a walk on Health app on iPhone without Apple Watch?

On a job site today and, not wanting to test my Apple Care + yet, left my new Watch at home.

Was taking a walk about and wanted to record it in the Activity section of the Health app. I found the way to manually add a completed event, but no way to start an active event without the Watch.

Is there a way to do this using Apple's native Activity applications?

I am aware that the app should have recorded my steps without having an activity running, which is some benefit. Yes, I know there are other apps out there, but I like the simplicity of Apple's own and minimizing my data distribution.

Thank you.
