howto use sdl3 shader api

[jcy1001]

when i use sdl2 an sdl_gpu lib (SDL_gpu)[https://github.com/grimfang4/sdl-gpu] i can use shader process my image like this
GPU_Image* image = GPU_LoadImage("data/test3.png");
Uint32 color_shader;
GPU_ShaderBlock color_block = load_shader_program(&color_shader, "data/shaders/common.vert", "data/shaders/color.frag");
int color_loc = GPU_GetUniformLocation(color_shader, "myColor");
GPU_ActivateShaderProgram(color_shader, &color_block);
update_color_shader((1+sin(t))/2, (1+sin(t+1))/2, (1+sin(t+2))/2, 1.0f, color_loc);
GPU_Blit(image, NULL, screen, screen->w/4, screen->h/4);

    ,now How do I apply shaders to images in SDL3, and is there any demo code available?
