MSFS_C152 Community (V1.0.0!) - Updated: 09/10/2021

Getting this topic back to life.
I’m now trying to use the JPL C152 addon in its latest version (Feb 2023 I think?) in MSFS2024.
The aircraft seems to work reasonably well, but I cannot get the copilot to show. Actually, both in external and internal views, the seats remain empty, no matter the options set on the EFB.
Anybody else having the same problem ?
