Is it possible to implement a cell click timer in Google Sheets?

Question

Spreadsheets

I click on the cell to the right of the task, the countdown has started (without visualization), the color of the cell has changed. I clicked again, the countdown stopped, the color returned to its original color. On the second click, the cell is filled with the time difference between the current and previous clicks. If the cell already had some value, then they are summed up.
