@bikassaha The current implementation is when the user confirms to restart
of an interpreter the modal button text changes to "Saving Settings" with the
spinner-icon and modal is there until the API response returns the status on
that bases we show the color (circle) -> green, red, yellow.
Do we need to close the modal after the user confirmation and then show the
blinking green (circle)?---
