I want to draw a point in the lower left corner of the map window (canvas). I tried the geometry genarator in the layer attributes:

point_n(@map_extent, 1)

This works, but I want the point really to be in the corner and not just the symbol. I need this, because I want to be able to klick on the point to select it. I tried to write the map extend coordinates in an virtual attribut field (x and y) to catch them with a Virtual Layer and this query:

Select id, make_point(x, y, 31256) as geometry FROM Koordinaten

Unfortunately this doesn't work. Has anyone an idea on how to solve this? Thank you for any hint.
