Hey @Dylan-Prins,
please excuse the delay. The module owner @mjrich19 should've reviewed your PR, but is maybe out on vacation.
That being said, thank you very much for your contribution. In general, the PR looks good to me. Normally I'd ask you to please also attach a workflow badge that shows hows that the static tests passed, but given the nature of the change it's quite obious that they'll pass.
Regardless, I'd ask one change of you that I'll comment on the files themselves.
