It is required that the primary_key be called "id"?

I was doing a simple crud with ci4 and everything went very well until I noticed that to eliminate some element of a table from the forced field table the primary_key has to be called "id"


This is the function that I use to eliminate

elimination of public functions ($ key) {
$ this-> crud_model-> delete ($ key);
return redirect () -> to ("/ crud");
}

When I see the error between a system / Model.php and I see that there is a global variable called primaryKey with "id" as the default value.

My question is, what should I do to be able to use that function without my primary key field being called "id"?
