First, I don’t really support private support questions, because my time is limited. Also, posting in the community publicly helps people to learn. Next time please don’t message me if you have a question…post it to the community and I will have a look, unless if it is urgent.
Second, such extension is already available in the App Inventor community. Courtesy @Sunny_Gupta.
@Taifun Tagged you. Can you add this to the extensions directory? Thanks.
