ZSE50 Integration Error (zse50 Integration 'zse50' not found.)

I just added three Zooz ZSE50 chimes (chime1, chime2, chime3) into Home Assistant Z-Wave JS (zwave-js-ui: 11.5.2, zwave-js: 15.15.3). I want to set different tones (mp3 files) for different events (e.g., motion on driveway, front door open). Member Hanson shared a script to send specific tones as part of an automation action.
Programming ZSE50 siren in automations

I am adding this as an !include zse50.yaml in the configuration.yaml file. My test adaptation code:

My problem is when I enable the zse50.yaml in the configuration.yaml, HA throws an error when I Check configuration, “Configuration warnings Integration error: zse50 - Integration ‘zse50’ not found”

However, when I go into Settings | Devices & Services | Entities, the entity shows up for the chime (siren.chime3_play_tone) as a Z-Wave Integration.

Not sure where to go from here or what the error is telling me. Any help would be appreciated!
