Completely uninstall integration?

I installed the Battery Notes integration from HACS to check out if it would work for me. i decided I did not have enough time to dedicate to testing it right now, so i removed the integration (deleted all the battery_notes entities it created, then I restarted, then went into HACS, and deleted it from there, and restarted again. Now, every once in a while, i get this in my logs:

i’ve used the shell to check my entire /config folder for any file that has battery_notes in it, and nothing shows up anywhere. I thought maybe some browser cookie may be keeping that alive, but i also deleted all the cookies in the browser and re-logged into HA, but the error persists. anyone have an idea on how to make the error go away?

I’m guessing here, but possibly some browser/CompanionApp needs to have a hard refresh in order to remove some lovelace card or similar that is still using a websocket regarding the battery notes.
