Use openGl with the raylib abstraction

[rmcvid]

Hey everyone,

I'm trying to work with OpenGL through raylib, but whenever I use an EBO it doesn't work at all. For example, I wrote a small test based on the tutorial from https://learnopengl.com/
I'm trying to draw a square made of two triangles indexed with an EBO, but nothing shows up.
I've included the code below.
Does anyone have an idea why the square isn’t rendering?

float vertices[] = {
    -0.5f, -0.5f, 0.0f, //bot left
     0.5f, -0.5f, 0.0f, // bot right
    -0.5f,  0.5f, 0.0f, // top left
    0.5f,  0.5f, 0.0f   // top right
};
unsigned int indices[] = {
    0, 1, 2,  // first triangle: bot left, bot right, top left
    1, 3, 2   // second triangle: bot right, top right, top left
};

int main(void)
{
    InitWindow(800, 600, "Shader carree");
    SetTargetFPS(60);

    const char *vs = "#version 330 core\n"
        "layout (location = 0) in vec3 aPos;\n"
        "void main()\n"
        "{\n"
        "   gl_Position = vec4(aPos.x, aPos.y, aPos.z, 1.0);\n"
        "}\0";
    const char *fs = "#version 330 core\n"
        "out vec4 FragColor;\n"
        "void main()\n"
        "{\n"
        "   FragColor = vec4(1.0f, 0.5f, 0.2f, 1.0f);\n"
        "}\n\0";

    Shader shader = LoadShaderFromMemory(vs, fs);
    int locColor = GetShaderLocation(shader, "ourColor");


    // gen -- Load bind except for the vao one; 
    unsigned int vao = rlLoadVertexArray();                                  // generate but don't assign 
    unsigned int vbo = rlLoadVertexBuffer(vertices, sizeof(vertices), false);
    unsigned int ebo = rlLoadVertexBufferElement(indices, sizeof(indices), false);
    
    // no need to enable other it is done in the load function
    rlEnableVertexArray(vao);
    // set
    rlSetVertexAttribute(0, 3, RL_FLOAT, false, 3 * sizeof(float), 0);
    rlEnableVertexAttribute(0);

    int countFrame = 0;
    while (!WindowShouldClose())
    {
        BeginDrawing();
        ClearBackground(BLACK); 
        rlEnableShader(shader.id);
        rlEnableVertexArray(vao);
        //rlDrawVertexArray(0, 3);                   // from the vao it works but not from the ebo draw 3 vertices
        rlDrawVertexArrayElements(0,6,0);     // draw nothing
        rlDisableVertexArray();
        
        EndDrawing();

        countFrame++;
    }
    UnloadShader(shader);
    rlUnloadVertexArray(vao);
    rlUnloadVertexBuffer(vbo);
    rlUnloadVertexBuffer(ebo);
    CloseWindow();
    return 0;
}
