How do I mirror my Samsung Galaxy M20 to my monitor if the screen or touchscreen doesn't work?

Hey everyone. I have a Samsung Galaxy M20 which a few months ago it's screen broke in a fall and now the only thing there is on the screen are dead pixels and lines. After that incident I bought another phone but I was wondering how could I mirror my old broken phone? I already have an USB-C to HDMI adapter, and I have actually mirrored the phone to my monitor before it broke. However now the screen and digitizer don't work. I don't even know if the phone's starting up correctly or if it had a software issue because my screen is really broken. It's nothing too important. Just wanted to see some photos I had saved on it and retrieve them. Whenever I plugged it in nothing happens. Im not sure if you had to confirm to mirror it or something like that, but it isn't doing anything.

​

Any help would be appreciated!
