How do I refer the current user in the Node expression?

Basically, I have a usecase, where I’m allowing a few team members to perform a write action on my App DB. In this, I want to store the team member’s name in my db who initiated that particular workflow. Is there an expression I can use (for eg: {{logged_in_user_name}} in my API call which would return the user’s name who is trying to use that workflow?

Hey @Saransh_Agarwal, welcome to the community! I am not sure I fully understand your scenario, maybe you can explain this a bit further?

Will your team member send API requests to n8n (possibly the webhook node)? Or how exactly would your team members interact with your database (and where does n8n come into play)?
