Lambda function missing

Dear AWS Support,

I recently created a schedule using EventBridge to automate investment tasks on Coinbase, following a tutorial provided here: https://www.youtube.com/watch?v=Oh6v-ELzA-g&t=694s. Upon returning to AWS to make modifications, I noticed that all my Lambda functions seem to be missing. I also noticed the IAM polices and roles associated with the tasks I am talking above are still on record. Despite being missing, these tasks seem to be active and placing investments every month. Could you please assist me in locating and modifying these functions?

Thank you for your prompt attention to this matter. Sincerely, Giselle
