如果需要NAPI C++层业务，调用 ArkTS层的类静态成员、静态函数，怎么交互实现

static napi_value TransObect(napi_env env, napi_callback_info info) 
{ 
size_t argc = 1; 
napi_value js_cb; 
napi_get_cb_info(env, info, &argc, &js_cb, nullptr, nullptr); 
​ 
napi_value str; 
napi_create_string_utf8(env, "John", 4, &str); 
napi_set_named_property(env, js_cb, "sMsg", str); 
​ 
napi_value staticMethod; 
napi_get_named_property(env, js_cb, "staticMethod", &staticMethod); 
napi_call_function(env, js_cb, staticMethod, 0, nullptr, nullptr); 
​ 
return nullptr; 
}

import testNapi from 'libentry.so'; 
​ 
class tsClass{ 
static sMsg:string = "Hello"; 
static staticMethod() { 
console.log('Static method called. sMsg = ' + tsClass.sMsg); 
} 
} 
​ 
@Entry 
@Component 
struct Index { 
@State message: string = 'Hello World'; 
​ 
build() { 
Row() { 
Column() { 
Button('Test') 
.fontSize(50) 
.fontWeight(FontWeight.Bold) 
.onClick(() => { 
testNapi.transobject(tsClass); 
}) 
} 
.width('100%') 
} 
.height('100%') 
} 
}

export const transobject: (a: Object) => void;
