Where is the code that unindents an empty list item on enter?

[OliverWales]

In the list playground, pressing enter when in an empty list item reduces the indent level by one until it is not indented, at which point it resets to a paragraph node. I'd like to achieve something similar in my own custom list plugin, but I'm having trouble finding which bit of the code implements this behaviour. Can anyone point me in the right direction?

I'm pretty sure it's this line in insertBreakList
https://github.com/udecode/plate/blob/main/packages/list/src/insertBreakList.ts#L33

Brilliant, thank you @12joan!
