Modifier with tab

[noahfraiture]

Hello,
I'm trying to make some keymap with some modifier and tab to switch buffer

"tab" = "goto_next_buffer";
"S-tab" = "goto_next_buffer";
"C-tab" = "goto_next_buffer";
"C-S-tab" = "goto_next_buffer";

In this list of keybinds, only the first one works. I have keymap with Ctrl, like C-h that works fine. But when combined with tab, it doesn't work anymore. Tab and other keys are used in my hyprland configuration but only when combined with the modifier Super key.
Do you know why it might not work ?
