What are the necessary actions to demonstrate remorse to God, given that remorse is one of the conditions for repentance?

Realizing remorse means genuinely wishing you had not committed the sin and feeling sorrow for having done so. This sorrow affects a person, making them wish what they did had not happened. Remorse is considered one of the conditions and the greatest pillar of repentance. It refers to regretting the sin because it is a sin, not for any other purpose.
