$ cat Consts.h

#ifndef CONSTS_H
    #define CONSTS_H

    namespace Consts
    {
        inline constexpr int Test_v = 120;
    }
#endif


$ cat Consts.cppm

module;

#include "Consts.h"

export module Consts;

export namespace Consts
{
    using Consts::Test_v;
}

$ cat Main.cpp

#include <iostream>
import Consts;

int main()
{
    std::cout << Consts::Test_v;

    return 0;
}


$ g++ -std=c++20 -fmodules-ts -x c++ -c Consts.cppm

$ g++ -std=c++20 -fmodules-ts Consts.o Main.cpp
Main.cpp: In function ‘int main()’:
Main.cpp:7:26: error: ‘Test_v’ is not a member of ‘Consts’
    7 |     std::cout << Consts::Test_v;
      |                          ^~~~~~


N.B. I also believe is a dup of pr109679
