How to mock the expect object class in KMM project

Expected Behavior

Be able to mock the expect object class in the KMM project

Current Behavior

In my shared module, I created a use case class that uses the expected object class to do things like read and write files. But when I follow the guide book(https://notwoods.github.io/mockk-guidebook/docs/mocking/static/) to mock the read and write operations, according to the debug result, it does not seem to excute the result of my mock instead of excuting the real operation.

Steps to Reproduce

1. create an expect object class in common module and use case class

The part of the use case class:

class UseCase {
  fun needToTest{
    ...
   if(FileOperation.mvFile(scr,dest)){
    ...
   }
    ...
}
}

The example file operation class:

  expect object FileOperation {
    
    fun rdFile(path: String): List<Path>?
   
    fun mvFile(srcPath: String, destPath: String): Boolean?
     ....
  }

android Part

  actual object FileOperation {
       ......
     actual fun mvFile(srcPath:String, destPath: String): Boolean? {
       ......
     }
      .......
  }

ios part

   actual object FileOperation {
   .......
   .......
}

2. Start to test the function of the use case

The example mockk method what I used currently

val useCaseTest = mock<UseCase>()
mockkObject(FileOperation)
every{ FileOperation.mvFile(srcPathMock, any())} returns true
when{
  useCaseTest.needToTest()
}

class Test {

    @Test
    fun test() {
        val useCaseTest = mock<UseCase>()
        mockkObject(FileOperation)
        every{ FileOperation.mvFile(srcPathMock, any())} returns true
        when {
          useCaseTest.needToTest()
          }
    }
}

Accoding to the debug results in my local, it doesn't seem to use the mock action I set up in the test function but instead does the real file operation.
