Hi! I have a requirement and couldn't find a proper solution or article anywhere. We are a third party service/ web app which integrate with Salesforce for exchange of Sales data. We have a javascript button in Salesforce Classic Integration which on click initiates a webservice apex class and sends an email as part of webservice call. We are planning to migrate Javascript buttons in Lightning version as they are no longer supported. However, when a Lightning experience converter check is done it says that conversion type is MANUAL. It has provided some examples on Github but that doesn't align to our flow. Can somebody please help ASAP as we are planning to migrate sooner? @Kevin Noschang  @Jenna Goldman  @Narender Singh  @Coby Press  @Diego Moreno
