Once you have icon, it will be beautifuly show in the launcher What mobile launcher are you using, how will you design the TW layout launcher?
I don’t know how you can export JSON manually, maybe use Gacha? I only know how to use Modern.TiddlyDev.
@Alren22 managed to do this, but with the wrong format. Release a plugin in proper format · Issue #5 · twcloud/tiddlyweb-sse · GitHub
Maybe you can install github-action-ts-run-api and tw5-plugin-packer from npm and use this script https://github.com/tiddly-gittly/Tiddlywiki-WikiText-Plugin-Template/blob/master/scripts/run-action.mjs
And you can create a new release in Releases · BurningTreeC/TiddlyFlex · GitHub , then upload the JSON there, if created manually. Or add a vx.x.x tag in git commit and modern framework will build json and upload it for you.
