How to expand the custom library when starting drawio

[messi1]

Hi
I have a typescript github project which embedds drawio into it.
When I start my application the custom lib is always closed.
I tried various settings but it still closed when I start the application.
Has anyone an idea? Thanks for the help.

private configureDrawio() { const configurationAction = { action: 'configure', config: { defaultFonts: [ "Humor Sans", "Helvetica", "Times New Roman" ], ui: 'min', // kennedy, atlas (default), dark and min darkMode: false, defaultLibraries: 'CoReTM', defaultCustomLibraries: ['CoReTM'], enabledLibraries: ['CoReTM'], expandLibraries: true, enableCustomLibraries: true, enableCssDarkMode: false, libraries: [{ "title": { "main": "CoReTM" }, "entries": [{ "id": "CoReTM", "title": { "main": "CoReTM", "de": "CoReTM" }, "desc": { "main": "CoReTM", "de": "CoReTM" }, "libs": [{ "title": { "main": "CoReTM", "de": "CoReTM" }, "data": coretm }] }] }], } } this.drawio.send(configurationAction); }
