Hi @FezVrasta,

Thank you so much for your contribution!

It seems, that there are some Typescript related errors on your branch: https://github.com/storybookjs/storybook/actions/runs/4718179558/jobs/8367500690?pr=21859#step:4:437

I'll send a fix in a minute

I'm sorry I can't get eslint to work locally, it complains about the storybook preset missing even though it's installed. If someone else could fix the formatting errors and get this merged I'd be grateful.
