Can MAGMA compute pullbacks of $kG$-modules?

Question

Let $G$ be a finite group and let $k$ be a finite field of characteristic $p>0$ such that $p\mid |G|$.

Let $M_1, M_2$ and $M_3$ be finitely generated $kG$-modules.

I read in the MAGMA online manual that MAGMA can compute pullbacks, but the function provided there works for the input types ModAlg and ModAlgFldElt, respectively.

Unfortunately, I was not able to let MAGMA compute a pullback when given two $kG$ homomorphisms $f: M_1\rightarrow M_3$ and $g: M_2\rightarrow M_3$.

Therefore, I'd like to ask:

Can MAGMA compute pullbacks of $kG$-modules?

Thanks for the help.

I tried the following, but got an error message.
