Is there a program that gives an ideal in the ring of integers that is not principal and coprime to $23N$ for $N \in \mathbb{N}$?

Question

Consider the quadratic number field $K=\mathbb{Q}(\sqrt{-23})$. Is there a program in sage that gives an ideal in the ring of integers that is not principal and coprime to $23N$ for some $N \in \mathbb{N}$? So far I have

sage: K.<a> = QuadraticField(-23)
sage: K.ideals_of_bdd_norm(5)

which gives me all ideals in $\mathcal{O}_K$ up to norm $5$.
