Viewing output and error logs from web app

I have deployed a Python-Flask web app in render which is connected to a PostgreSQL database. The web app is working but how do I check the output and error logs from my python code? I have connected my account to logtail but it does not show these. For example, if the python code writes something with print then how do I check the output from the deployed app?

Hi there,
Anything written to STDOUT will appear in the log output for your service which you can view at https://dashboard.render.com/web/srv-ccfmnfha6gdgjihi96kg/logs
