I want to create button, that if someone clicks it should show how many times it clicked, also when other person comes to that page it should start from last clicked number and when he clicks that number should increase from last clicked number.
eg. 1st person clicked button 10 times and at that time counter is started from 0.
Result after last click: 10
2nd person clicked button 5 times at that time counter starts from 10. Result after last click: 15
