Doesn't work in Linux Kubuntu 22.04

[OnkelTem]

Sorry for not following the bug template, because it doesn't even start recording.

I'm on Linus Kubuntu 22.04 LTS
Nothing special.

As far as I can tell - every needed service is functioning properly:

• pipewire.socket
• pipewire.service
• pipewire-media-session.service
• xdg-desktop-portal.service

All are active and running.

Yet the app doesn't record with message:

Caused by:
    0: Failed to create session
    1: Interaction was ended in some other way with response Variant { ptr: 0x5bca2ecbe2b0, type: VariantTy { inner: "a{sv}" }, value: "{'session_handle': <'/org/freedesktop/portal/desktop/session/1_43553/kooha_2'>}" }

This is additional info I found in the menu:

- io.github.seadve.Kooha 2.3.0
- Flatpak: true
- Experimental Features: []

- Language: en_US, en, ru, C

- CPU: <unknown>
- GPU: NVIDIA Corporation GA104 [GeForce RTX 3060 Ti Lite Hash Rate] (rev a1)

- Distribution: GNOME 46 (Flatpak runtime)
- Desktop Session: plasma
- Display Server: x11

- GTK 4.14.5
- Libadwaita 1.5.5
- GStreamer 1.22.12
- Pipewire 0.3.83

What I do wrong?
