I installed Sourcetree onto my Mac computer for the first time. I used my login to log into the bitbucket cloud. When I finish logging into the system for Sourcetree, it said there is no ssh key but there is. How do I get my existing key to be implemented within the source tree because I do not want to create a new key. I went through the process of granting access for Sourcetree to use bit bucket and I thought i had everything transferred over including the SSH key. I am using Sourcetree version 4.2.1. (248) ... I will upload screenshots to give you a better understanding.
