I have already read everything, but I can not find a clear answer and a solution to the problem
.

<input id="mysubmit" type="submit" value="submit" onclick="mycoolfunc()">

the mycoolfunc function is in a separate file, it is connected to <head> <script>, it is registered in the manifest, but due to the CSR, chrome does not allow the inline function to be executed

document.addEventListener('DOMContentLoaded', function () {
  document.getElementById('submitbutton').addEventListener('onclick', mycoolfunc);
});

doesn’t work or I’m doing something wrong
the documentation says about the sandbox, but what’s what - I can’t understand , tell
me, please
