In this video I work with a test project in a GeoPackage that includes styles, tools, layouts and some example data. I create MGRS grid reference vector layers and style them with QGIS, and create layouts with MGRS grids.


The project (GeoPackage) can be downloaded from https://plugins.qgis.org/geopackages/7/
On the plugins site you can also find the included QGIS models as separate downloads if you don't need the entire project.
