@bosd first time creating a pr so hopefully I did it right. Also, I just learned about .toml files and I'm not sure how to go about testing this change on my end. From my understanding of how these things work, I think this is the correct change.

Thanks, I will report back after some sleep.
Manually adding to the toml file is an option.

But it is also needed to update the lock file.
From the cli it is possible to let the package manager make these changes to both files.
I think we're using UV package manager now.

After some reading on uv, it looks like it is a terrible option tbh. I'll close this one and make a new with properly generated files.
