the code question

[127xudada]

Why does the Code link in "Multicopter Swarms Planning: youtube or bilibili. (Reported by IEEE Spectrum Website!) Code" not point to the code of the paper in the video, but to ego planner v2?
Where is the open source code for this article 《Decentralized Spatial-Temporal Trajectory Planning for Multicopter Swarms》 which commits that "The software will be released after the reception of our previous work(GCOPTER) for the reference of the community" ?
Thanks !
