Setting / editing / changing / manipulating local bash variables inside fzf execute()

[MikeLemo1]

I'm basically trying to make a somewhat of a file explorer based of fzf that with single fzf execution I'll be able to reload fd entry and toggle between files or directories and in different directory entries and in order to do that I'll need some way of declaring variables inside fzf execution (Through the command opts) but I'm struglling with changing/setting a variable to be able to then read off of it and toggle / use it as an entry in the fd query
Also but I't quite related I'm trying to use the fzf Prompt as a variable and query toggler but since my working across a 2D matrix option I need finer read control access to each word(divided by space " ") and access it similar to ${FZF_PROMPT[2]} to say access the second or third word it the ${FZF_PROMPT} but first you need to declare it into another array like; MY_ARR=($FZF_PROMPT) which I'm not sure how to do and tryed with execute() with no luck.
Any idea?

I'm also trying to execute internal function say myFunc() { echo "Test from the other side successful" }
but not sure how to...

Dumb question...
Just have to use ; between var declaraction and a command e.g.:

• Prints the third element of the $FZF_QUERY after it's been split and "arrayed" into MY_ARR

  --bind "ctrl-r:execute: MY_ARR=($FZF_QUERY) ; echo ${MY_ARR[2]}"

where I instead tryed using |, ||, &, &&
Closing.
