Click the More Filters button in the sidebar on the left, and in Actions and Opportunities > Flop > Flop Raises you can filter for "Raised Donk Bet".
That will show you all hands where you raised a donk bet.
If you want to see how often that raise won immediately you will need to add more filters - for example NOT 'Saw Turn' AND NOT 'faced a raise on the flop'.
You can't see success/failure as a percentage with filters, but you could do that with a custom stat.
For example, I duplicated the existing "raised donk" column and made a new version like this:
cnt_f_donk_def_opp_action_raise_success =
sum(if[lookup_actions_p.action LIKE '%R' AND tourney_hand_player_statistics.amt_f_bet_facing > 0 AND NOT (tourney_hand_player_statistics.flg_f_open_opp) AND substring(lookup_actions_f.action from 1 for 1) = 'R' AND NOT tourney_hand_player_statistics.flg_t_saw AND NOT tourney_hand_player_statistics.flg_f_face_raise, 1, 0])
