Python unittest patch unable to mock

I am trying to patch a property of a class with some mock value, but when I run the test case the function or class that is using that property is not replacing it with the mock that I have created.

Module property that I need to mock

class Mymodule:

    @property
    async def calling_property(self):
        return "Calling the property"

the class that is using this module.

class Usecase:

    async def execute(self):
        module =  Mymodule()
        data = await module.calling_property
        print(data)

the test case I have written

import unittest
from unittest.mock import patch, AsyncMock,PropertyMock


class TestModule(unittest.IsolatedAsyncioTestCase):

    async def test_execute(self):
        with patch("users.usecases.medical_device.update_medical_device.Mymodule",
               **{"calling_property":AsyncMock(return_value="calling mock")}, new_callable=PropertyMock
               )as mock:
            a = Usecase()
            await a.execute()

As you can see i am logging the response from the property in my usecase, so when I run my test it is logging "calling the property" rather than "calling mock".

I tried another way.

class TestModule(unittest.IsolatedAsyncioTestCase):

    async def test_execute(self):
    with patch("users.usecases.medical_device.update_medical_device.Mymodule.calling_property",
                new_callable=PropertyMock,
               return_value= AsyncMock(return_value="calling mock")
               )as mock:
            a = A()
            await a.execute()

This gives separate error

TypeError: object AsyncMock can't be used in 'await' expression

I have also tried creating a mock for the class object

class TestModule(unittest.IsolatedAsyncioTestCase):

    async def test_execute(self):
        with patch.object(Mymodule,
        "calling_property",
        new_callable=PropertyMock,
        return_value=AsyncMock(return_value="calling mock")
               )as mock:
       
            a = A()
            await a.execute()

TypeError: object AsyncMock can't be used in 'await' expression
