regex - How to search and Replace multiline string inside big multiline string in javascript

Question

i am using fs module to write and read file

I have a big js file with code that I have converted to a string. I want to edit the contents of this file and replace the following lines of code:

};
export default unidentifiedClassName;
const unidentifiedClassName = {   

I am using js replace to edit string. Is there any way I can edit this multiline code since I cannot replace it?

let unnecessaryCode = `};
export default unidentifiedClassName;
const unidentifiedClassName = {`; 

modifiedCode = modifiedCode.replace(new RegExp(unnecessaryCode, 'gm'), '#');

console.log(modifiedCode);

It should also ignore extra newlines and spaces before or after each line
