Also, without trying to sound like an asshole, if you need something like Notion, better use Notion I guess, Obsidian does a lot of things differently. OTOH, if there is a solid reason for you to move away from Notion it should definitely be possible.
Maybe as a start, you can look at what this framework does. It tries to implement the PPV system, that was originally created for Notion. But be warned, I think this is absolute overkill, if you haven’t really put much thought into the way you manage your notes, it’s just meant to show, that someone more or less managed to get a Notion-like experience in Obsidian
