Skip the title of the theorem but leave the [].

[Francesco-2003]

Hi,
I would like to be able to write the theorem with the [], but without writing something in it, I would like to leave it blank and still be able to use the theorem, without latex which tells me that there's an error.

This is the discussion when another one originally posted the same question:
https://tex.stackexchange.com/questions/657340/how-to-skip-the-title-of-a-theorem

Thanks for your report. I've added an answer to your tex-sx question.

It may take more time to conform if this is a bug or some undocumented "feature".

Hi, Thank you for the answer, It works if you put your code in the Preamble of latex, but it doesn’t work when you try to put it while changing the Theorem style, for example in the “answer” I posted, I report that.
