Hi,
you can try this :
There is a custom action on the
Ecosystem called iterate it is mainly used to loop.
Get the length of the string then use this on the iterate end index, leave increment to 1 and store the current index.
in the next state use "get string left" and use the "current index" on the char count. then use array add and then loop the state back to iterate,
add another state for when iterate is done.
It is possible that you need to set the start index to 1 on the iterate and / or add 1 to the string length i can't test this atm
If you don't understand what i mean, let me know so i will make a quick video to explain.
