How appwrite functions actually work how to trigger those functions from client side

**here is the client side code ** const handleSubmit = async () => { console.log("Form submitted:", { landlordId, tenantDetails, selectedProperty, selectedUnit, }); debugger; try { const inviteCode = Math.floor(100000 + Math.random() * 900000).toString();

  await database.createDocument(
    config.databaseId,
    config.inviteCollectionId,
    ID.unique(),
    {
      code: inviteCode,
      landlord_id: landlordId,
      tenant_phone: tenantDetails.phone,
      property_id: selectedProperty.property_id,
      status: "pending",
      created_at: new Date().toISOString(),
      expires_at: new Date(Date.now() + 24 * 60 * 60 * 1000).toISOString(), // Expires in 24 hours
    }
  );
  console.log("invite added into database");
  // Execute Appwrite Function to send SMS

await functions.createExecution( "6727a2e1001f2c7ade1c", // Replace with your function ID JSON.stringify({ phone: tenantDetails.phone, code: inviteCode, }), false, "sms", ExecutionMethod.POST ); // console.log("Function executed successfully", res); alert("Invitation sent successfully!"); router.push("/"); } catch (error) { console.error("Error sending invite:", error); alert("Failed to send invitation. Please try again."); } };

i have already created a function in console and pass that function id into the createExecution method

but i want to know how this excution is trigger and how can i test it
