How to incorporate axesm-based maps in an app

I am interested in creating axesm-based maps:

h = axesm('MapProjection','mercator')

However, there appears to be no way to tie the axesm object back to a parent app container:

h = axesm(app,'MapProjection','mercator')        % doesn't work

I need to reference the various app components, for example:

app.panel.earth = axesm(app.panel,"Geoid",grs80, "Grid", "on");        % or something

There are lots of examples of how to use the other axes(), but not so much for axesm.

I intend to create, move and destroy lines in the app. I know how to do this in a UIAxes component, storing the line segments in Children. But axesm still throws me. I started with this example, but now I need to fold it into a GUI app:

There is no straight-forward way of doing this. axesm() does not have anything similar to a 'Parent' property. axesm() is written in terms of gca

To use axesm with a uifigure() you need to work around the fact that uifigure HandleVisibility is Off

fig = ancestor(app.panel, 'figure');
fig.HandleVisibility = 'on';

Then you have to have an axes within the panel, and make it the current axes

ax = findobj(app.panel, 'type', 'axes');
if isempty(ax)
    ax = axes(app.panel);
end
fig.CurrentAxes = ax(1);

Then you can axesm

h = axesm('MapProjection','mercator');

This is great! Encapsulating the axesm() with an axes makes it dual-purpose, and I can do UIAxes-type functions on it. Thanks.
