It's works for me:

 class MyStatic {
  static group:Record<string, (s:string)=>string> = {
    name:(value:string):string => {
      return value;
    },
    age:(value:string):string => {
      return value;
    }
  }
}

interface ObjProp {
  value:string;
  label:string;
}

const values:ObjProp[] = [{value:'nameValue', label:'name'}, {value:'ageValue', label:'age'}];

for(let m of values) {
  const Value = MyStatic.group[m.label](m.value); 
  console.log(Value)
}

Rather than

MyStatic.group[m.label as keyof ObjProp]();

you probably wanted

MyStatic.group[m.label as keyof typeof MyStatic.group](); 

however, both methods still need an argument, e.g.

MyStatic.group[m.label as keyof typeof MyStatic.group]('foo');
