could be setup in the esp_websocket_client_config_t or with a custom handler like in the CJSON to override:

memoryHook.malloc_fn = spiram_calloc;
memoryHook.free_fn = spiram_free;
cJSON_InitHooks(&memoryHook);

// Wrapper calloc SPI RAM.
void* spiram_calloc(size_t size) {
void* ptr = TRACEABLE_HEAP_CAPS_CALLOC(1, size * sizeof(unsigned char), MALLOC_CAP_SPIRAM);
if(ptr == NULL) {
printf("Fail alloc SPIRAM\n");
}
return ptr; // return NULL if TRACEABLE_HEAP_CAPS_CALLOC fail
}

void spiram_free(void* ptr) {
heap_caps_free(ptr);
}

so in the hooks the way to handle the memory could be lead to user to choose, or just like a flag in the esp_websocket_client_config_t as:
.memorytouse = 0 (0, internal, 1, external)

I have sent an pull request proposal to the maintainers.

send, so, if you need to use external memory in websocket, now it is full working like a charm.,
