Adjusting mouse coordinates in on_click event

I`m trying to create a game with a map, that is dragable with the mouse and has some clickable "buildings" on it.

So I know I need to add the camera viewport lower left corner coordinates to the mouse position, to get the world and screen coordinates adjusted. But i don´t know how to do this, like how to manipulate the mouse coordinates in the on_click / UIMouseEvent and how to constantly add adjustment to the current mouse position to cover hover events as well.

ok found the solution meself:

I created a class inheriting from the arcade.gui.UIManager

class UIManagerPlus(arcade.gui.UIManager):
    def __init__(self, window: arcade.Window | None = None):
        super().__init__(window)
        self.cam_lower_left_x = 0
        self.cam_lower_left_y = 0

    def adjust_mouse_coordinates(self, x, y):
        return (x + self.cam_lower_left_x), (y + self.cam_lower_left_y)

class MyView(arcade.View):
    def __init__(self):
        super().__init__()
        self.manager = UIManagerPlus()
        self.camera = arcade.Camera2D()
        ...

    def on_update(self):
        self.manager.cam_lower_left_x = self.camera.bottom_left.x
        self.manager.cam_lower_left_y = self.camera.bottom_left.y

Im using arcade 3.0.0.dev29, where the new Camera2D is implemented
