Shortcut for Square Mode?

Hi rbowZ28, thanks for the informations. Unfortunately, there are translation problems for the various steps in Tasker. It’s confusing because I’m using a German version of Tasker.
The only thing I know for sure is that I can put a Tasker widget on the home screen. I use Nova myself, I know my way around - but unfortunately this is only the last step.
So I’m going to ask point by point, please forgive the lengthiness of this post.
You: “What I did is use the “event” action, when I open the “app” to perform a task, square mode, circle mode, etc.”
My Question: Event is in German “Ereignis”, but what does it mean: “When I open the ‘app’ do perform a task…” What is “the ‘app’”? And above all the main question: How and WHERE do I find “a task, square mode, circle mode, etc.”???
I haven’t found an app (and no event) where I can choose between square and circle mode. That seems for me the main problem.
You: “You can also create tasks without defining an action” - I don’t understand this.
As I said in my previous post, I do understand the following steps: Create Profile – Event (Ereignis) - System/Custom Setting[Type: System - Name: watch_small_screen_stat - Value: =:=toggle=:=]
But the rest remains obscure to me. Hopefully we can fix the translation issues. Thanks anyway.

@rbowZ28
Sorry for my impatience, but I would like to ask again if you can offer me a solution to the problem described above. Thank you!

It can be done, you can put it on the desktop, for example I use nova,You can also switch at any time using a floating icon

Production Method
in tasker
This is called long pressing the power button

,Step 2 Click on the fixed coordinates
Or use fixed gesture points,Gesture clicks are more stable
