# Acro package: use serif font and alignment?

I am using scrbook and want serif fonts for chapter headings etc.

When I am using acro package, the acronyms are not printed in serif font similar to the section heads as defined by:

\addtokomafont{disposition}{\rmfamily}


Could someone please help me out here, so that the acronyms are printed in the same serif font and ideally could also tell me, how to align the long form of the acronyms to the longest acronym used?

MWE:

\documentclass[paper=A4,
pagesize,
DIV=calc,
openany,
BCOR=8mm,
numbers=noenddot]
{scrbook}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{palatino}
\usepackage{acro}

\DeclareAcronym{OASIS}{
short = OASIS,
long = Organization for the Advancement of Structured Information Standards}

\DeclareAcronym{SOAP}{
short = SOAP,
long = Simple Object Access Protocol}
