Hi Chinju,
Could you provide a more specific description of your problem or attach a screenshot? It would help us solve it.
If you have problems with default save button then you can try to replace it with your own button, in which you call a microflow to save and refresh the object.
Use a microflow action to save the context object. On commit of that object, refresh the object.
Or as a last resort close and open the pop up again.
Regards,
Ronald
