Query: On cyclic left modules and arbitrary bimodules over the octonions   Qinghai Huo, Yong Li, Guangbin Ren described the structure of left
$\mathbb{O}$-modules in great detail in arXiv:1911.08282. However, they left
open a question on cyclic left $\mathbb{O}$-modules. This note intends to close
this gap and provide a complete description of bimodules.
