Just click the icon again to switch to placing big 'final' decisions (you can erase any of these too in case you change your mind). Just click the 'note' icon - now every number you put in a cell will be a small note alongside other candidates. Just like in a paper Sudoku, you can make 'small pencil notes' in the cell of which numbers can go there. No matter what trick you use the most helpful thing for solving a Sudoku is 'penciling the candidates'. Now draw a horizontal and vertical line from every 4 on the board (you remember you can't place another 4 in a row or column) - it will quickly become clear there are almost no cells left where you can actually put it. Choose a number that occurs most on the board already (so there's one or two instances left to place) - there are indicators below the board to help you find the best one.

Just place 3 and look across the whole row, then the column: is there a duplicate? Try the same with 7 and you'll get the correct option. For example, if a 3x3 square lacks just the numbers 3 and 7, we have only two options on how to place these two remaining numbers - 3 in a first cell and 7 in a second one or vice versa. You will certainly see a square where just one or two numbers are missing.
