No, not off topic.
In fact, the OP question could be the preliminaries to a book.
And, this is my second flag.
The first one was because I shared a Microsoft Windows link to “How to create an Icon”, dated from August 2020 (or so), but in the text (I read it after sending the link) was talking about using Freehand by (name of the 20/30 years ago owner).
The OP says it “used a Vectorial software to create its icon as was writing somewhere” and that document says… exactly that.
Back to off topic: I received (last year I think) an off topic answer that was exactly what I needed. My question was not incorrect. The answer was. And I thanked the answer’s author. I was really happy.
BTW: thank you Markus for telling me I was flagged. I could stay many days without knowing that as I will leave home tomorrow and I do not really know when I will come back…
At last, in another Topic, in a screen shot the OP set a “Cancel / Stop” button (macOS) at the window’s right: I do not answered.
