Gutenberg custom block plugin with custom image sizes
I am using a custum gutenberg block plugin for wordpress(https://neliosoftware.com/blog/how-to-create-your-first-block-for-gutenberg/)
This block is using an image but always choosing the full size image. I would like that it chooses custom image sizes like the standard gutenberg image or gallery blocks. when browsing the web I can’t find any plugin for Guteberg with these options. Can you give me any suggestion on how to get these functionalities? Is it even possible?
Thank you for all your efforts to help me.
