Can't figure out looking ahead

[IsotoxalDev]

I am creating a parser based on PEST. in that it was created like:

I tried a number of ways to do it in Tree sitter by doing precedence and choice. Also looked into external, but i want rules I have written in the grammer.js file to check or rewrite entirely in scanner.cc which would make it work but would lead me to spent another 8 hours(it took that to just do the same in grammer.js)

What is some example input you are trying to parse, what is your desired syntax tree, and what is the syntax tree you are getting instead?

[IsotoxalDev]

Test {
   plaint_text till a comment // A comment
  plain_text till multiline comment /* A
Multiline Comment */ plain text till another element start Elem {A new element}
plain text till end of svope
}

Expected tree

element
  plain_text
  comment
  plain_text
  comment
  plain_text
  elememnt
  plain_text

Okay, what have you tried and why does it not work?

[IsotoxalDev]

        plain_text: $ => /(.|\n)/,

        element_start: $ => seq(
            $.namespaced_identifier,
            optional($.element_id),
            repeat($.element_class),
            optional($.element_attributes),
            $.curly_bracket_open
        ),

        structure_child: $ => choice(
            $.component_element,
            $.structure_element,
            $.style_element,
            choice(
                prec(3, choice(
                    $.element_start,
                    $.comment,
                    $.curly_bracket_close,
                )),
                prec(2, $.plain_text),
            )
        ),

This is what i tried and it gives the whole source cod as an error
