		-Disclaimer: This workload is provided as-is and might need further configuration and customization to work successfully in each unique environment. For further Professional Services-based customization please consult with the Login VSI Support and Services team. Please refer to the Help Center section "Application Customization" for further self-help information regarding workload crafting and implementation.
		-Run the workload against the "target" using Script Editor to ensure it will work before uploading it and testing with it
		-Go through the workload to understand what it's doing. Comment out any unneeded app tests (code blocks) or add on any needed functional testing
		-Workload version and changelist:
		--V1.0 | original
		-Leave Application running compatibility: true
		Notes: 
		-Please read each of the commented-out portions of this script, to see what it does and if there are lines which should be commented out or changed (variables, for example)
		-Environment: Win 10 Pro x64 winver 1909 18363.720 | Slack for Windows version 4.4.0 | Login Enterprise ScriptingToolset version 4.0.11
		-Google Chrome browser is optional to be installed -- if Slack needs to be logged into/authenticated via a web browser, then Chrome will be needed (or another web browser, but the script will need to be customized to support it)
		This script will:
		-Start Slack for Windows (desktop GUI) and ensure it's started
		-Look for the Sign In button, but move on if not found
		-If the sign in button is present it will process the defined sign in process, with the defined user credentials, into the defined workspace.
		-If Sign In button not present then the script will assume the workspace is already logged into, and just continue on with the defined workload actions thereafter
		-Interact with the logged in version of Slack desktop, verifying it has opened successfully to the landing page
		-Open the defined Slack channel name by clicking on it
		-Click on the new message field after the defined Slack channel has been opened
		-Send test messages, with the defined loop amount, into the Slack channel via the message field
		-Close out of Slack for Windows
