Marking Class Properties as Mutable in Effect Typescript

I noticed that my methods in classes cannot mutate properties:

class Thing extends Schema.Class<Thing>('Thing')({
  property: Schema.String.pipe(Schema.mutable)
}) {
  public update() {
    this.property = "New Value"
      // ^ error TS2540: Cannot assign to 'property' because it is a read-only property.
  }
}

class Thing extends Schema.Class<Thing>('Thing')({
  property: Schema.String.pipe(Schema.mutable)
}) {
  public update() {
    this.property = "New Value"
      // ^ error TS2540: Cannot assign to 'property' because it is a read-only property.
  }
}

Is there a way to mark some of the properties as mutable at all?
