Preventing clickjacking vulnerability from client side

Question

What other options do I have to prevent clickjacking, I am looking for possible solutions that can work on the codebase not server side.

I am working on an angular project and have tried these,

setting "X-Frame-Options": to "sameorigin" and even "deny" and also http-equiv="Content-Security-Policy". content="default-src 'self'; frame-ancestors 'self';" and also

but this error is always shown, they my sit still gets loaded on a frame.

The Content Security Policy directive 'frame-ancestors' is ignored when delivered via a <meta> element.

I have also tried to check for window-top against window-self and if it does not match sop that screen from opening further.

The idea here is that I do not want to make any of these changes server side, but on the code level. If there are related questions or one that works please also help with directions there, or the question is not clear kindly comment and I will try and give more descriptions.
