Hi. I need your helps.

I am trying to upload my app on Prolific. 
I should upload URL, but do not know which URL is needed.

Should upload URL which is given by python when I operate 'heroku main push' (ex. https://myapp.heroku.com), 
or Session-wide demo link(ex. https://myapp.heroku.com/join/brrrr)?

DO USE the session-wide participant link that oTree generates after you create a new session.

In addition, I recommend using oTree HR: https://hr.otreehub.com/
