Toasts Tasker Layout: Image Aspect Ratio

It looks like the Icon for a Flash in Tasker Layout is always assumed with Aspect Ratio 1:1.

I have an Image rather 16:9, and want to show it big. it doesn't get stretched, but with empty Borders Top and Bottom. The Text is aligned Top. Not really nice :-p

Is there a Way to prevent emtpy Space Top/Bottom?
Not just one Number for the Icon Size, but maybe 60x30?
Or a HTML/CSS Code i didnt try, that helps me with that?

Similar goes for Text/Title. It looks like its alignment is fixed to TopLeft within the Toast. Things like:

<div style="text-align: center; display: flex; align-items: center; justify-content: center; height: 100%;">
    Text
</div>

don't work here as well.

I know i could set up a Scene, but that will make Things so much more complicated. Im hoping there is a Way to influence how the Image gets displayed in a Toast.
