How to modify backref format in biblatex?

Trying to get backref to work with biblatex with KOMA, I came up with the following code:

 documentclass{scrbook}
 
 usepackage[natbib=true,backref=true,style=ieee]{biblatex}
 
 usepackage{hyperref} addbibresource{sample.bib}
 
 DefineBibliographyStrings{english}{   backrefpage={See p.},  
 backrefpages={See pp.} }
 
 
 begin{document}
 
 chapter{Chap 1} Some textcite{greenwade93}. 
 
 
 printbibliography
 
 end{document}

where DefineBibliography allows me to modify how the citation reads. Going from

 . D. Greenwade, “The Comprehensive Tex Archive Network (CTAN),”TUGBoat,vol. 14, no. 3, pp. 342–351, 1993 (Cit. on p. 1).

to

 . D. Greenwade, “The Comprehensive Tex Archive Network (CTAN),”TUGBoat,vol. 14, no. 3, pp. 342–351, 1993 (see p. 1).

But how do I remove the parentheses in between (see p. 1)? Or how do I modify the formatting further so that the numbers become superscripts with nothing else for example? I cannot find it in the manual.

documentclass{scrbook}
usepackage[natbib=true,backref=true,style=ieee]{biblatex}
usepackage{hyperref}
addbibresource{sample.bib} 
DefineBibliographyStrings{english}{
  %  backrefpage={see p.},
  backrefpage={},
  %  backrefpages={see pp.}
  backrefpages={}
}
renewcommand*{finentrypunct}{}
usepackage{xpatch}
%DeclareFieldFormat{backrefparens}{mkbibparens{#1addperiod}}
DeclareFieldFormat{backrefparens}{raisebox{4pt}{scriptsize{#1}}}
xpatchbibmacro{pageref}{parens}{backrefparens}{}{}
 
begin{document}
chapter{Chap 1}
Some textcite{greenwade93}.
newpage
Some textcite{greenwade93}.
printbibliography
end{document}
