Thank you for your contribution, yet it cannot be approved because it does not follow the Utopian Rules.
While I liked what you are trying to teach and accomplish here, yet few things led to the rejection, as follows:

• you mentioned in the tutorial that this part will handle removing and editing deletions, yet you mention nothing in this regards within the post
• your code has absolutely no comments about what you are doing. This is essential in teaching others about what you are doing and basic programming requirement

Also note that steemconnect actually accepts SP instead of vests, under the same param, so no need for the conversion function and you can send 100 SP as the value the param and it would be accepted.
