JabRef 5.x Custom Export Filter


I’m new to JabRef 5.x. I have a personal Export Filter that converts .bib files into .html using some .layout files. According to JabRef 5.x doc, I should add the filter as below
OptionsManage custom exports. However, I do not have such a tab under Options. All I have under Options are: Preferences, Manage content selectors, and Customize entry types. Please advise.


The custom export filter can be added as below
OptionsPreferencesCustom export formats. Click on Add and provide the Export format name, the path to the main .layout file, and the File extension.
