How to export a grease pencil to mesh?

I’m trying to export my lines for a game


I tried to use the addon
GreasePencilToUnity
but got it

I had to manually fix the normals AND edit the mesh but this is all I got

The line turned out very torn and crooked

Is it possible to turn a pencil into a normal mesh?
Or
grease pencil->polygon curve->mesh
And after thicken the “ribs” of the mesh from all sides by making it a long cylinder

The Solidify doesn’t help
