apology guys , was finding a proper screen recorder software , and after finding one , faced file size problem .
so just made a quick video and the description is here .

description

first i have added two beecons
first one is the old one with the title of menu
and the other one is with new title which is the new one .

after that i went into settings of the old qbw to see the id to show that it is being removed .
then pressed x to delete the old beecon from the desktop
then i went into the settings of new qbw and then hit the advance button on the bottom right corner and then pressed yes and then it asked you to remove it completely and then pressed yes , it will remove the old beecon .
and then i added a new beecon to show that it is adding new beecons now .
