My approach to seperate js and css file from embedded form don't seem to work

I am using a camunda spring-boot starter project, where I am suppose to put javascripts to “src\main\resources\META-INF\resources\webjars\camunda\app\tasklist\scripts\demo.js” then refer them in the config.js like this:
customScripts: [
// // If you have a folder called ‘my-custom-script’ (in the ‘tasklist’ folder)
// // with a file called ‘customScript.js’ in it
‘scripts/demo.js’
],

in the embedded form, I refter to demo.js like this (probably wrong here)
and I put my styles in
“src\main\resources\META-INF\resources\webjars\camunda\app\tasklist\styles\user-styles.css”
also don’t seem to work. can someone help with these two.
