Problems With Remote Desktop Connection

I'm currently running a 2019 windows instance on macOS as I am running software that I can't use on macOS on my Windows Instance. Whenever I want to connect to my EC2 instance, I have to download a new RDP file because it won't launch automatically even though I've downloaded the SSM Agent onto it. Is there anyway I can get it to connect to my instance automatically instead of me having to download a new RDP file and manually entering the password each time?
