System Configuration
Kubuntu 20.04
KDE Plasma 5.18.8
Linux kernel 5.4.0-105-generic

Background
I used KDE Menu Editor to create separate shortcuts to open three different Google Chrome profiles (i will refer to them as Work, University, and Home). I then added these shortcuts to my Application Launcher favourites so that they appear in three different Plasma Activities, one for each of Work, University, and Home. This all works fine.

Requirement
I want to pin the Google Chrome shortcuts to the Task Manager in each of the Plasma Activities, so that I can open the correct profile quicker while I am in a specific activity.

Problem
I can pin the shortcuts to the Task Manager, but when I click on it, it does not open the intended profile. Rather, it opens Google Chrome's profile selector window that asks me "Who's using Chrome?"

Request
Please help me find a way to pin the Google Chrome shortcuts to my Task Manager in the different activities so that they open the intended Google Chrome profiles.

Many thanks for your help.
