If its a space with more than one participant, if you click on the "Waffle" icon on top right, select "Meetings", it should give you the link to join a specific space. I am not sure if this is what you are after or looking for shortcuts within the Spark application.
Thank you George for your reply. Your advice is helpful but not exactly what I need.
What I need is a link for a space that I can send via chat or email that will direct them to the team space.
