Rich Winter kindly pointed out an error in one of my posts.
He also suggested adding my Twitter handle to the blog.

Thus, I’ve included a new button to the index page. The button leads to my Twitter account.

It’s only visible on the index page, not on the individual blog post pages.

My blog uses the Gatsby blog template by LekoArts.
I don’t want to deviate from the design too much as I like the minimalist style.
