How do I setup Supercharged Links plugin in Obsidian?

What I’m trying to do

I’m trying to setup the Supercharged Link plugin so I can colour code my links by tag. But it’s not working.

Things I have tried

I downloaded and installed both the Supercharged Links plugin and the required Style Settings Plugin. I looked at the plugin instructions and multiple youtube videos but the setting look really different on my screen.

I don’t have the styling section it’s just not there at all. I can’t add a ‘New Selector’. I tried turning off the theme I had set back to the default one but still my menu looks different.

If someone could please help me with this I would be really grateful! This has been driving me crazy :sleepy:
