Spotify doesn't set `app_id` attribute when runs on Wayland

[StayPirate]

Description

Spotify only sets name attribute if started in Wayland, but that field changes when a new track is played. Hence, it cannot be used to track its window in script like 2ca84ae.

As soon as it starts:

              "name": "Spotify Premium",
              "window": null,
              "nodes": [],
              "floating_nodes": [],
              "focus": [],
              "fullscreen_mode": 0,
              "sticky": false,
              "pid": 1141275,
              "app_id": "",
              "visible": true,
              "max_render_time": 0,
              "shell": "xdg_shell",
              "inhibit_idle": false,
              "idle_inhibitors": {
                "user": "fullscreen",
                "application": "none"
              }

once a track starts playing

              "name": "Meganoidi - Zeta reticoli",
              "window": null,
              "nodes": [],
              "floating_nodes": [],
              "focus": [],
              "fullscreen_mode": 0,
              "sticky": false,
              "pid": 1141275,
              "app_id": "",
              "visible": true,
              "max_render_time": 0,
              "shell": "xdg_shell",
              "inhibit_idle": false,
              "idle_inhibitors": {
                "user": "fullscreen",
                "application": "none"
              }

Solution

I need to investigate to understand how to set a static app_id value.
