I´ve prepared a not-so-short video on how to work with backend functions & triggers in REI3. Its about 50 minutes in length, so please feel free to skip around with the video chapters.
English: https://youtu.be/JjVNA67pEWU
German: https://youtu.be/TXgXO6zoV8k
This is the first video for experts we´ve released - I hope some will find it helpful.
