Animating travelled path in QGIS without any temporal information and without temporal controller

In QGIS, I have a path (line layer) that I want to animate: it should succesively build up like showing a point marker that "drives" along the line and shows (unveils) the part of the total line covered so far. Like drawing the line with a point marker.

The problem, however, is that I do not have any temporal information, the. The path should just be drawn at a constant speed.

Using geometry generator, one can build the substring of a line using the function line_substring(). How to use this to create such an animated line?
