Icons,Theming and Font Issues in Qt Snaps Lubuntu

I am using Lubuntu 22.04.1 with Lxqt 1.2.0, since lxqt is a qt desktop env, one should expect proper theming for atleast Qt apps, but Qt snaps like Vlc,Okular,Kcalc,Kate etc. wont use the system specified Kvantum Theme and also the fonts in the apps is small and ugly , in flatpak with the help of xdg-config overrides we can atleast apply kvantum themes on Flatpaks but on Snaps i didnt found any such thing. So Qt apps from Snap store wont use the system fonts,cursor or themes. I am using Kvantum Style, but Qt apps cant use it,even classic Qt snaps like kate wont use my icon set for interface, i.e, Papirus_Dark, same is for cursor @Breeze_Snow and Fonts Ubuntu Regular 13. Output of Snap VLC after forcing Kvantum to it :

[00005584681e0b10] main libvlc: Running vlc with the default interface. Use ‘cvlc’ to use vlc without interface.

QApplication: invalid style override ‘kvantum’ passed, ignoring it.

Available styles: Breeze, Windows, Fusion

VLC SNAP :(Theming issue)

KATE SNAP: (Fonts and Icon issue)
