org.freedesktop.IBus interface not found in the system after installing ibus and daemon start

Question

My system is Kali 2022. I am new to linux and trying to interact with IBus using a python script. I have done the following things:

1. Installed ibus using sudo apt install ibus
2. Started ibus-daemon using ibus-setup which prompt me start ibus-daemon through gui.

And then I wrote a python script to list all the input-engines available to ibus system. When I run the script I get interface not found in org.freedesktop.IBus

Then to identify the problem, I have installed qdbus package and run qdbus in terminal as it will let users to list available services and objects, inspect interfaces. I get the following result :

 org.mozilla.firefox.L2hvbWUvc2hpbWFudHRhLy5tb3ppbGxhL2ZpcmVmb3gvaXlmZWl3eW4uZGVmYXVsdC1yZWxlYXNlLTI_
    :1.68
     org.freedesktop.IBus
    :1.69
    :1.70
     org.freedesktop.portal.IBus
    :1.71
     org.freedesktop.IBus.Panel.Extension.Gtk3
    :1.72
    :1.73
    :1.74
    :1.81
     org.xfce.mousepad
    :1.89
    org.freedesktop.DBus

Above I can see an entry called org.freedesktop.IBus present. But when I attempt to get the objects exposed by this service, I get the following :

$ qdbus org.freedesktop.IBus

/

Also systemctl command to check ibus-daemon service's status, returns no such service running even though I've started ibus-daemon.

└─$ systemctl status ibus-daemon
Unit ibus-daemon.service could not be found.

Following is the python script:

import asyncio
from dbus_next.aio import MessageBus
from dbus_next import BusType

async def main():
    bus = await MessageBus(bus_type=BusType.SESSION).connect()
    introspection = await bus.introspect('org.freedesktop.IBus', '/')
    ibus = bus.get_proxy_object('org.freedesktop.IBus', '/org/freedesktop/IBus', introspection)
    ibus_iface = ibus.get_interface('org.freedesktop.IBus')
    print("Successfully connected to IBus D-Bus service.")
    # List engines
    engines = await ibus_iface.call_list_engines()
    print("Available engines:", engines)

    await bus.disconnect()

asyncio.run(main())
