I feel like a scrub asking this, but does anyone have a good solution for syncing iCloud calendar events to Exchange calendars?

Context: I occasionally have to schedule telehealth appointments during work hours. Maybe one time in 5, I either work through the appointment because I’m zoned into work context and miss the notification on my phone, or accept a work meeting in the same slot, and have to bail on work when folks are expecting me to be there.

What I need:
To take events on my personal calendar (iCloud) and put them on my work calendar (Exchange)
Ability to see event times
Events to be interpreted as times I’m not available for scheduling purposes

What I’d like:
Only sync event times with work, not event details

What I don’t need:
Exchange to iCloud sync

What I don’t want:
A third party service that I have to link my calendars to.

Addendum:

I also don’t want and won’t use vibe coded bullshit… apparently timely since somebody just released this in the last 24 hours, which could theoretically be abused for my purposes.
