I Installed Howdy for my IR camera and when I try do "sudo howdy test" I get this error,

Opening a window with a test feed

Press ctrl+C in this terminal to quit
Click on the image to enable or disable slow mode

Authorization required, but no authorization protocol specified

qt.qpa.xcb: could not connect to display :1
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

I know this is related to something regarding qt version mismatch but I'm unable to find what exactly should I do, can some one please help me out? I installed it from AUR, using sway and 6.1.5-arch2-1 kernel

~~Why are you running it as root? Run it as your regular user while in a graphical session.~~

edit: nevermind, the wiki does say to do that - however I still suspect that's the problem. You may need sudo flags to export / preserve the relevant environment (e.g., DISPLAY).
