Unable to install mods on Linux because of drag-drop issue

Compiled from source, launches fine and identifies the installed steam version, but unable to install any mods. Dragging a pak-file does nothing, and there doesn't seem to be an alternative way (like a menu, context menu, or button) to install mods.

/etc/lsb-release: DISTRIB_ID=Zorin DISTRIB_RELEASE=17 DISTRIB_CODENAME=jammy DISTRIB_DESCRIPTION="Zorin OS 17.3"

Using GNOME Files (on Wayland) as file manager. Also tested from Thunar without luck. Both installed using apt, so no flatpak shenanigans either.

There really should be a clickable button or something. Or even CLI.

On a side-note, running the Windows exe through wine, drag-drop works fine, but then it can't find steam instead. A GUI option for manually telling it where/how to run steam might be an option?

Here's the complete log file after starting the compiled program, trying to drag-drop a few pak-files (both multiple and single), and then closing it:

I think this might be related:

• https://github.com/emilk/egui/issues/4255

Tracked it down through your dependencies. You should really add a button.

[cravl-dev]

I agree that there should be a button. I have the same issue on KDE Neon (base 24.04) with Dolphin, both with Wayland and Xwayland.

In the meantime however, you can install mods manually by dropping them in ~/.local/share/Astro/Saved/Mods.
