refresh 3D views inside a script loop

I try to write a tool to bake all IK keys of a rigify armature to FK keys
Basically, I use the IK to FK function, I create a rotation key on FK bones, and I move to next keyframe. Easy!

It works with the current frame, but when I need to iterate between keyframes, the 3d view doesn’t refresh, and all FK keys are the same. If only I could refresh the view, I feel it would solve my issue. But no way…

this my code :

import bpy
lastkey = -10
bpy.context.scene.frame_set(0)


while bpy.context.scene.frame_current > lastkey:
    lastkey = bpy.context.scene.frame_current

#fk2ik function
    bpy.ops.pose.rigify_arm_fk2ik_z0gi8z8u886b3215(uarm_fk="upper_arm.L", farm_fk="forearm.L", hand_fk="hand.L", uarm_ik="MCH-upper_arm_ik.L", farm_ik="MCH-forearm_ik.L", hand_ik="hand_ik.L")

# big mess to try to update the scene, but visually, it don't works
    bpy.context.scene.update()
    bpy.data.scenes[0].update()
    bpy.context.scene.frame_set(lastkey)



# insert keys on FK bones, it works great if I stay at current time
    bpy.context.active_object.keyframe_insert(data_path='pose.bones["forearm.L"].rotation_euler')
    bpy.context.active_object.keyframe_insert(data_path='pose.bones["upper_arm.L"].rotation_quaternion')
    bpy.context.active_object.keyframe_insert(data_path='pose.bones["hand.L"].rotation_quaternion')
 
#move to next keyframe
    bpy.ops.screen.keyframe_jump()

self answer : it wasn’t exactly a refresh issue, but I had to set time before the Ik2FK function.
so now, it works like this :

import bpy
lastkey = -10
bpy.context.scene.frame_set(0)

while bpy.context.scene.frame_current > lastkey:
lastkey = bpy.context.scene.frame_current
bpy.context.scene.frame_set(lastkey)
bpy.ops.pose.rigify_arm_fk2ik_z0gi8z8u886b3215(uarm_fk=“upper_arm.L”, farm_fk=“forearm.L”, hand_fk=“hand.L”, uarm_ik=“MCH-upper_arm_ik.L”, farm_ik=“MCH-forearm_ik.L”, hand_ik=“hand_ik.L”)
bpy.context.active_object.keyframe_insert(data_path=‘pose.bones[“forearm.L”].rotation_euler’)
bpy.context.active_object.keyframe_insert(data_path=‘pose.bones[“upper_arm.L”].rotation_quaternion’)
bpy.context.active_object.keyframe_insert(data_path=‘pose.bones[“hand.L”].rotation_quaternion’)
bpy.ops.screen.keyframe_jump()
