Hey, I am a first-time contributor and I am having a really tough time trying to find where to make the modifications and how things piece together in order to make this work, let alone actually finding a way to solve it. Could anyone please provide some guidance on how to get started or point me in the right direction, I'd really appreciate any help!

Sounds like a duplicate of #61489. Maybe #61495 fixes this already?

Not the same case, #61489 is about the comma after the second argument, this is about comma in the second argument.
