Toolbar missing in custom missions

Hi – I’m new to working with custom missions and am running into a problem. I’m able to author custom missions, however, non of the missions can access in the ingame toolbar.

I believe it has something todo with not providing a correctly formatted mission script to go with the custom mission. I was wondering if someone could share a link to some docs I might be missing. I’ve been pouring over the mission definitions documentation (Mission Definitions), but it’s pretty daunting.

Running MSFS, build 1.37.19.0, SDK 0.24.3
Windows 11

In the mission script, you need to set a ‘flow state’. This describes what kind of flight/mission you’re in.

You can find documentation here: <SimMission.FlowStateAction>

Or you can use a template project that includes a flow state definition: SimpleMission (MSFS) - FSDeveloper Wiki
