I created a messenger type app with attachement, how do i make it so that they can hold the image and save it?

I tried everything and it doesn’t work.

Kindly show what have you tried…
BTW
You can use download component
Or screenshot component
Or Component to image extension [free] <need? Search for it>

If you are using chatview then there is a block named when chatview clicked. Use it and check that message contains image. If it contains image then use download component to download image.

And if you are using image component then there are two blocks for click named when image clicked and when image long clicked
