  In this paper we give an example of duoidal $\infty$-categories. We introduce
map $\mathcal{O}$-monoidales in an $\mathcal{O}$-monoidal $(\infty,2)$-category
for an $\infty$-operad $\mathcal{O}^{\otimes}$. We show that the endomorphism
mapping $\infty$-category of a map $\mathcal{O}$-monoidale is a coCartesian
$(\Delta^{\rm op},\mathcal{O})$-duoidal $\infty$-category. After that, we
introduce a convolution product on the mapping $\infty$-category from an
$\mathcal{O}$-comonoidale to an $\mathcal{O}$-monoidale. We show that the
$\mathcal{O}$-monoidal structure on the duoidal endomorphism mapping
$\infty$-category of a map $\mathcal{O}$-monoidale is equivalent to the
convolution product on the mapping $\infty$-category from the dual
$\mathcal{O}$-comonoidale to the map $\mathcal{O}$-monoidale.
