Harper not working in google keep (google notes)

Hey, Harper seems to not work at all in google keep. Is there a way to fix this, or is it an issue with the way the site loads text itself?

I usually write my documents in word, and then put them in google keep to spellcheck with Grammarly, but I just switched to Harper today.

If I need to use google docs, that's okay as well, but I would like it if Harper worked with google keep.

I am using brave browser.

Start by reproducing the issue in Brave with Google Keep, then compare the behavior with Google Docs, which the report says may work. Trace how the Harper browser extension handles text in these sites; done means Harper works in Google Keep or the compatibility limitation is clearly documented.
