@kuklick Hi!
I am sorry to hear that information from Velo does not meet your needs. Feel free to reply to their email with more questions.
Also, I would recommend checking the information on Velo Forum as there are a lot of code experts that can provide you with relevant information.
https://www.wix.com/velo/forum
There you can use search to check if someone raised the same question before.
Unfortunately, I am not a coder, so this is out of my scope
