Show loader on button once clicked until loaded/finished #2143
Description
related with #2142 change
In the future, it should be solved by a loader added to the triggering element (like button), the triggering element should be probably also disabled until the action is complete
This is quite essential to have especially in cases if modal is slow to load and it should be restricted to call it multiple times in parallel.
Currently nothing is shown until the modal is loaded, UX should be improved by showing loaded on the triggering button until the action is completed/loaded to keep the user informed the action click triggered an action.
