What's your preferred digital disimpaction method?

Do you go in with one finger, pierce through the stool ball and try and squish it around to break into smaller stool pieces?

Do you go in touching the side wall of anal canal and pull back the stool ball, breaking it into pieces on the way?

Or do you go in with multiple lubed up fingers and swish around in the anal canal and pull back?

Sorry nobody has taught me this and now I'm too embarrassed to ask. Unsuccessful digital impaction on shift today. : /
