BibLatex Chem-Angew Citation style with Postnote argument

Question

I'm using the chem-angew style in biblatex with footnote as described here. I now need the page number in the footnotes from which I have taken the corresponding information. How can I adjust the Chem-Angew Style so that when I specify a postnote argument, it is used as the corresponding page number? I didn't find an option like "citepages" in the documenation.

Here is a example:

\begin{document}
    Text \sfcite{Wortmann.2019}
\end{document}

Here is how I want it to look like:

So the page range of the whole article in the journal should be left out, so I can define a postnote argument with the page. Also the first 1.0 is not visible in my working document, don't know why it is on display in this example.
