Spring Missing documentation on how to migrate from @SpyBean to @MockitoSpyBean with Kotlin (problem with mock)

There is a documentation on how to use @MockitoSpyBean: https://docs.spring.io/spring-framework/reference/testing/annotations/integration-spring/annotation-mockitobean.html but the problem is how to use it properly with Kotlin - there are only examples with Java. Before Spring Boot 3.4 I was able to create and use mock with @SpyBean like that:

@Configuration
@SpyBeans(
    SpyBean(SomeProvider::class),
    SpyBean(SecondProvider::class)
)
class TestConfiguration

class TestSteps(
    private val someProvider: SomeProvider,
) {
    @Before
    fun before() {
        doReturn("value").whenever(someProvider).getSomeValue(any())
    }

Now that these annotations are deprecated, I want to migrate them to @MockitoSpyBean, should this look like that?

@Configuration
@MockitoSpyBeans(
   MockitoSpyBean(types = [SomeProvider::class]),
   MockitoSpyBean(types = [SecondProvider::class])
)
class TestConfiguration

class TestSteps(
    private val someProvider: SomeProvider,
) {
    @Before
    fun before() {
        doReturn("value").whenever(someProvider).getSomeValue(any())
    }

with above code the mocks aren't working anymore because of the error:

org.mockito.exceptions.misusing.NotAMockException: 
Argument passed to when() is not a mock!
Example of correct stubbing:
    doThrow(new RuntimeException()).when(mock).someMethod();

Tried this one and another solutions like creating mocks in fields inside this TestSteps class but none worked.

Could you provide right solution on how to migrate the code?
