missing in docs

[bitlab-code]

Hello, I'm try to add a simple toolbar with "Heading1" "paragraph" and "link" buttons
but i can't find any info into the docs.

I'm started from online official example but I'm able to add only a "bold" feat.
Can anyone please help me? Thanks

I used the playground editor as a starting point to figure out creating a toolbar
