What approach do you take to provide feedback within your team?

My name is Vio, and I am the co-founder of a mental health app designed to help individuals navigate challenges in their personal and professional lives. Our app offers self-therapy journeys crafted by top psychologists, each with unique expertise in addressing specific issues. We are a team of 7 at the moment and what I am looking for is to find the best solution for giving feedback to each other. Can you share how you do that in your team? (much appreciated)
