How call UFUNCTION (BlueprintImplementableEvent) from JS with EMSCRIPTEN and error: Module.ccall is not function?

I am making a game for HTML5. At a certain moment I call the ad block, before that I put the game on pause. When the player closes the ad block, I need to unpause the game (I use Blueprints). I need to call UFUNCTION (BlueprintImplemetableEvent) from JS, but I didn’t find how.

I use this code in cpp:

#ifdef __EMSCRIPTEN__ 
#include "SDL/SDL.h"
#include "emscripten/emscripten.h"
#include "emscripten/html5.h"
#else
#define EMSCRIPTEN_KEEPALIVE
#endif 

#include "string"
#include "iostream"
#include "sstream"

//'"FString Text" I assign to test in Blueprints

void AChristmasMole4_23CPPGameModeBase::Test()
{


	

	std::string OutboundSendString(TCHAR_TO_UTF8(*Text));




#ifdef __EMSCRIPTEN__ 
	EM_ASM_ARGS({
		var theText = UTF8ToString($0);

		console.log('Hello' + theText);
		}
		
		, OutboundSendString.c_str()
		);
	
	emscripten_run_script("testJS();");


#endif
}


extern "C" void EMSCRIPTEN_KEEPALIVE CallTest(char *str)
	{
	
//I don't know how to call UFUNCTION(BlueprintImplementableEvent) here
//I used (char *str) because I don't know how to use Module.ccall to call a function with no arguments

	}

In [ProjectName] -Shipping.UE4.js file:

function testJS()
 {
    var str = "Hi from JS!";
    var lenUTF8 = Module.lengthBytesUTF8(str) + 1;
    var ptr = Module._malloc(lenUTF8);
    Module.stringToUTF8(str, ptr, lenUTF8);
    Module.ccall('CallTest', 'null', ['string'], [str]);
    Module._free(ptr);
}

When I call the testJS() function, it shows that Module.lengthBytesUTF8 is not a function and Module.ccall too.

I’ve looked at a lot of threads on this topic but couldn’t find an answer to my question.

And my code knowledge is very noob.

I DID IT!!!

I didn’t call Module.ccall, but I was able to do without it.
I created an integer in an HTML file and placed it in the “HEAD”

<script>
        var numTest = 0;
    </script>

When the player presses the START button, the testJS() function is called.

in cpp:

#ifdef __EMSCRIPTEN__ 
	emscripten_run_script("testJS()");
#endif

in HTML:

<script>
function testJS(){
numTest = 1;
}
</script>

Each tick checks to see if numTest has changed to 1.
If numTest=1 then EventUnpause is activated and numTest returns to 0.

in cpp:

#ifdef __EMSCRIPTEN__ 
	int CallUnpause = EM_ASM_INT({
		return numTest;
		});


#else
	int CallUnpause = 0;
#endif



	if (CallUnpause >= 1)
	{
		Unpause();


#ifdef __EMSCRIPTEN__ 
		emscripten_run_script("numTest = 0");
#endif
	};
