Waveshare 4.3 inch HDMI no touch response

Hi friends,
I have a 4.3-inch Waveshare V2 HDMI display (clone?) connected to a Raspi3b and a Volumio.
The display works fine, but I haven’t been able to enable touch.
What should I do? I’ve followed the recommendations on this page: https://files.waveshare.com/upload/f/fd/4.3inch_HDMI_LCD_User_Manual_EN.pdf, but I haven’t had positive results. At one point, I got an error saying a component couldn’t be found when downloading and installing (I’m new to Linux).
Does anyone have one of these displays working and could help me out?
Thanks!

Good morning! It turned out to be my mistake. There was a step I wasn’t following during the screen installation process. It’s working fine now, although for me, it should have a larger screen.

Best regards, everyone!
