I am working on a sharepoint online classic team sub-site, and i added the React Script Editor webpart from https://github.com/SharePoint/sp-dev-fx-webparts/tree/master/samples/react-script-editor to allow me to add custom scripts inside modern pages. so i went to the sub-site's site content link >> i add the web part app, as follow:-
Sorry, something went wrong Sorry, this site can't be saved as a template. It contains apps that don't work in templates: Modern Script Editor web part by Puzzlepart
so my question is:- if there is a way to add the web part to my sub-site and at the same time to be able to save the sub-site as template?
