The morea template repo provides a subdirectory called
_module-icons containing over 50 PNG files that have been used in Morea sites as a module icon. You can preview these module icons here.

_module-icons directory into the directory containing the files for your module, then update the
morea_icon_url field in the front matter of your module.md file to refer to it.
