   //imagine
   const Imagine = await client.Imagine(
     prompt,

       console.log("loading", uri, "progress", progress);
     }
   );
   console.log(Imagine);
   if (!Imagine) {
     console.log("no message");
     return;
   }
   //U1 U2 U3 U4 V1 V2 V3 V4  "Vary (Strong)" ...
   //⬅️,⬆️,⬇️,➡️
   const V1CustomID = Imagine.options?.find((o) => o.label === "V1")?.custom;
   if (!V1CustomID) {
     console.log("no V1");
     return;
   }
   // Varition V1
   const Varition = await client.Custom({
     msgId: <string>Imagine.id,
     flags: Imagine.flags,
     customId: V1CustomID,
     content: prompt, //remix mode require content
     loading: (uri: string, progress: string) => {
       console.log("loading", uri, "progress", progress);
     },

   const U1CustomID = Imagine.options?.find((o) => o.label === "U1")?.custom;
   if (!U1CustomID) {
     console.log("no U1");
     return;
   }
   // Upscale U1
   const Upscale = await client.Custom({
     msgId: <string>Imagine.id,
     flags: Imagine.flags,
     customId: U1CustomID,
     loading: (uri: string, progress: string) => {

     },
   });
   if (!Upscale) {
     console.log("no Upscale");
     return;
   }
   console.log(Upscale);
   const zoomout = Upscale?.options?.find((o) => o.label === "Custom Zoom");
   if (!zoomout) {
     console.log("no zoomout");
     return;
   }
   // Custom Zoom
   const CustomZoomout = await client.Custom({
     msgId: <string>Upscale.id,
     flags: Upscale.flags,
     content: `${prompt} --zoom 2`, // Custom Zoom  require content
     customId: zoomout.custom,
