Make Zod.string() handle empty string as undefined

Having a schema like

z.string().min(4)

z.string().min(4)

I want

""

""

to throw

Field X is required

Field X is required

and

"abc"

"abc"

to throw

Field X must contain at least 4 characters

Field X must contain at least 4 characters

.

But I don't want to add this specifically to every prop.
Can I somehow make Zod handle

""

""

as "not defined" by default?
