How remove tag <script in external javascript?

i wrote the popads external javascript code in my blog by linking the github code link in jsdelivr, and it worked.
but jsdelivr is only used once, meaning that the code in github that is changed does not change the contents of the code in jsdelivr with the same file that has been linked.

I got the popads code itself from the popads api URL.
url

<a href="https://www.popads.net/api/website_code?key={my-api-code}&website_id={website-id}&tl=always&aab=1&of=1"> https://www.popads.net/api/website_code?key={my-api-code}&website_id={website-id}&tl=always&aab=1&of=1</a>

url results display

<pre>
<script ***>
popads code
</script>
</pre>

how do i remove <script> tag?
