And as noted, it might have been during a sling operation?
It is a person standing in an elevated position. After the initial mishap the person jumps in two steps down to the platform. This was already described in the original French article, before the close-up video appeared online. In the close-up there is also some activity at the lower left corner of the outer structure of the lighthouse platform, faintly visible, but if one looks closely it appears to be the line, or part of it.
