How to run an application without a terminal, but with additional settings?

Question

linux

Through the terminal, I launch a discord with additional settings that remove microphone noise, but how can I set this up by default, for example, for the entire system or at least for one application?

Here is the command: In `/etc/pulse/default.pa` specified the following configuration:
PULSE_PROP="filter.want=echo-cancel" discord

load-module module-echo-cancel source_name=noechosource sink_name=noechosink
set-default-source noechosource

load-module module-echo-cancel source_name=discord sink_name=discord
set-default-source discord

But they do not help and you have to run through the terminal

Answer 1

The easiest way to set this variable is in ~/.profile (for a specific user) or /etc/environment (for everyone).
export PULSE_PROP="filter.want=echo-cancel"
And reboot the system. After that, you can launch Discord as usual through the GUI.

Answer 2

Well, for example, by creating an icon on the desktop

In the line Exec=/path/to/executable/file, you can write anything, any parameters, incl. the path to bash that runs the script with the desired application and all the settings.
