Did Josh have no involvement in The Line?

It sounds like Tyler wrote it all in 3 days and Paul helped with the production and Josh was not mentioned at all. So did he not even do the drums? In that case shouldn’t it be The Line by Tyler Joseph and not by Twenty One Pilots?

If it was a Tyler solo song we would all know it wasn’t lore related and just a lovely song he did as a side project for a TV show and about his grandmother.

Idk it’s just weird to me to have a TOP song with no Josh involvement, but maybe most of the songs don’t have much to do with him?
