Hello, and thank you for sharing the code! 👍
However, the license is not specified, making the code essentially closed source.
This can be fixed in many ways, the most common being a LICENSE file in the root of the repo (recognized by GitHub). GitHub guide.
(If the author does not specify a license, the rights to the work are 100% owned and controlled by the author.)
(Both FAI and FLY have this issue, so opening issues on both of the projects.)
