TYPO3 Core

My current Workaround in the main method of RTE plugin:

  $pageRenderer = GeneralUtility::makeInstance(\TYPO3\CMS\Core\Page\PageRenderer::class);
  $pluginName = $this->pluginName;
  $packagename = GeneralUtility::underscoredToUpperCamelCase($this->extensionKey);
  $jsCode = "define('TYPO3/CMS/Rtehtmlarea/Plugins/$pluginName',['TYPO3/CMS/$packagename/Plugins/$pluginName'],function (Plugin) {return Plugin;});";
  $pageRenderer->addJsInlineCode($this->extensionKey . $pluginName . "_workaround see https://forge.typo3.org/issues/77698",$jsCode);

As the RichTextElement loads your requireJS module anyway, the workaround could be done without changing the RTE plugin by simply adding the line

define('TYPO3/CMS/Rtehtmlarea/Plugins/YourPluginName',['TYPO3/CMS/YourPackageName/Plugins/YourPluginName'],function (Plugin) {return Plugin;});

at the beginning of your requireJS module JavaScript File.
This still stays a workaround, though.
