Expected Wait Time for AI Agent Workflow Creation

First timer here. Entered a set of parameters in the AI Agent builder and says "give me time to build the workflow..." after answering a few clarifying questions. The workflow isn't wildly complicated--researching people on Linkedin and creating 2 separate lists. I've been waiting about 10 minutes so far. How long should I expect this to take? Is it frozen? If it really does take this long, can I work on other agents while this one is building?
