How to find out the command to run the program?

Question

linux

Slack is for work. I remember that when you first launched the program through the command line, you had to enter a command starting with x. Now I can’t remember this command, I launch Slack through a shortcut. The "slack" command in the terminal does not work, it says:
"The "slack" command was not found, but can be installed with:
sudo apt install slack"
I understand that he offers to install the program?

If I view the list of processes through the top command while Slack is running, then in the COMMAND column it is written like this - slack. Tell me how to find out what command it eventually starts? And how can you change it?

writes like this "/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=slack --file-forwarding com.slack.Slack --enable-features=WebRTCPipeWireCapturer @@u %U @@"

1. Create a file /usr/bin/slack and open it with a text editor
2. Write:

#!/bin/bash
/usr/bin/flatpak run --branch=stable --arch=x86_64 --command=slack --file-forwarding com.slack.Slack --enable-features=WebRTCPipeWireCapturer @@u %U @@

Press Apt + F2 and enter the name of the program (slack).
If there is one, then the command to run it will be found.
