verify Table ID type in a form with zod

I want to submit an id of convex type 
Id<"part">
 with a form. I'm doing form validation with zod and wondering what is the best way to do this. If i use 
z.string()
 for the part ID, typescript complains that 
string
 can not be assigned to 
Id<"part">
 when calling the mutation function. This sounds reasonable, as the mutation indeed expects an argument of type 
Id<"part">
.

I get correct types and no typescript error when using 
z.custom<Id<"part">>()
 to validate the field. But I think I still need to add a validator function to this custom type, because zod says 
If you don't provide a validation function, Zod will allow any value.
 I can add a manual check to make sure the provided value is indeed a string, and maybe check length and whatnot. But I'm wondering if I'm missing something here... Is there a best practice for a scenario like this?
