I need to restore my Brave bookmarks after updating my Mac

I stupidly installed the Mac Sequoia beta a month ago. And, since then, I’ve added both applications and bookmarks to Brave. I discovered, painfully, that to fully update to the new Sequoia Mac OS, I had to clear out my Mac and reinstall the OS and my contents. I’ve done all that. But, Brave is missing all of my bookmarks. Does anyone know how I can get them back? I wish they were synched to the Cloud in some way.
Thanks.

After googling around, someone suggested going to my Brave bookmarks on my iPhone. Then, pressing the share button to export them. But, there is no share button.
