How to put google custom search Engine in custom block plugin?

I put the following codes from CSE as is, but no search box seen?

I am not familiar with tech. Probably there must be very simple.

The content in the custom block plugin is probably sanitized and the script part is of course the problem there. See Differentiation of HTML-capable text blocks

I guess one way would be to allow the use of script tag, but that is not a good idea. The other option is to write a small block plugin for the google search. It is not a big job, if you take some existing block plugin as the starting point.

Hello Ajnyga,
I have examined developedBy and some other block plugin, but unfortunately it is impossible job for me to write a google search plugin. I have no programmer skill, didn’t understand anything. Is there any way I can copy or replace?
