Hi @jklaise ,

I hope you're doing well. I wanted to express my gratitude for merging this pull request. I noticed that the 'hacktoberfest-accepted' label hasn't been added to it yet.

Hacktoberfest is important to many contributors, including myself, and this label helps participants track their contributions. If it's not too much trouble, could you kindly add the 'hacktoberfest-accepted' label to this merged pull request? This would be greatly appreciated.

Thank you once again for your support, and I look forward to contributing more to this project in the future.
