How do I get the value of @punctuation.delimiter?

I want to get information about the tree sitter. Among them, I want to get the value of @punctuation.delimiter . How can I get it?

In the above case, ":":",""." I want to get the string ":",";",",","".

It was made by the following method.

for _, match, _ in query:iter_matches(parent_node, 0, start_row, end_row) do
    for id, node in pairs(match) do
        if character_type == 'punctuation.delimiter' then
           -- Write the process here
