I thought it would be nice to post something about this topic, which is very useful but still a mystery for some. I recorded a video (tutorial + explanation) about what you can do with an Internal Communication.
The purpose of this blog is to collect all relevant information, tips, good practices, workarounds, etc. regarding Internal Communication.
You can find more details about it in the complete reference here.
Feel free to ask or share about IC!
Hope this helps. 🙂
