Creating a Manager Agent for Parallel Sub-Agent Execution in Lindy

Hi Support Team, my first post here. Exploring Lindy quite a bit and created some nice flows. Love the AI Agent focused approach (verses code all over). I am using it for basic app testing, using the computer, login and then press some buttons. Quite an evolution from what we have been doing for the last 30 years. I am able to get Agents working great.. and it does exactly what is needed. I am running in to challenges with creating a ‘manager’ agent that can start and run sub agents ‘in parallel’. I have tried conditions with more than one parallel exit(does not work) I have loops, one got stuck and ate all my credits.. so bad. Very brute force and not easy to scale and add additional. I am looking for the correct mechanism to enable a manager agent to start sub agents .. in parallel, and all run and then when all are done I generate a summary report. Can see how that would be useful and can have a suite of test cases running and then send a summary. Can someone share the right mechanism for this? Or even better a working example of pure agent to agent parallel invocation ? Really appreciate any insight here.
