Email a photo with minimal interaction

hello, I would like to build a very simple app that takes a photo (resize it) + a description and automatically send them to a preconfigured email address… I don’t know where to start or if anyone has a tutorial to follow…

could you help me?
thanks

take photo and Resize/compress image (function)

and Google Firebase - AppGyver - Rest API - #DIY-6 - YouTube

you first need to upload the image on storage and then send the link with email.
you can use this api

and take a look in this video on how to connect it
