Unable to transfer all my browser info from Safari to Brave

Hello

I am simply trying to transfer all my information from one browser, Safari, to Brave. I want to transfer the bookmarks and all my ID and passwords I use for emails as well. I followed some instructions that said to open Safari, go to File, go to Export Bookmarks and then save, however, a sign appeared that said it could not do it.

Thank you for advice,
