How can I remove the bufferline underline from the active buffer?

[andradei]

I'd like to remove this, what theme config (or any other) controls its styling?

I had this line one my theme:

"ui.statusline.active" = { fg = "fg.default", bg = "canvas.default", underline = { color = "scale.coral.3", style = "line" } }

Removing the underline part did what I want.
