Google Sheets: use of ImportXML to remove data from SimilarWeb

I'm trying to figure out how the importxml function is working, and so far it's quite complicated.

I am trying to delete specific data (the single user per month) from this website:*/999/3m?webSource=Total

I followed several tutorials that led me to find this XPath:

// *[@id=”__single_spa_angular_1″]/ div[1]/ div / div / div / div / div / div / div / section / div / section / div / div / div[2]/ div[1]/ div[5]/ widget / div / div / div / div / div[2]/ div / div / div / div[2]/ div[2]

However, when I use the function, it shows me an error or the content is empty. I'm not really sure what the cause of the problem is, but I would really appreciate some help in that regard!

Thank you !
