I am trying to create a web app in Python (Flask, tkinter etc), and perhaps a bit of HTML/CSS/JS. I can host this program locally but am not sure how to deploy this to SystemLink such that it is visible in SystemLink Web Server's Web Application section. This is in the web interface when you click on the 4-squares-icon in the top-left, drop-down 'Custom Applications,' and select 'Web Application'. Can you please help me with this? I haven't been able to find anything online specifically about this.
