My employer switched to Office365 & I logged into my Edge browser on my personal laptop with my work account.  Now, all of my history is showing up in:

History > Other Devices

It's also showing up on my work laptop.  How do I remove my personal private browsing history in the Other Devices tab?

Deleting the history doesn't work?
