User Feedback on a B2B Lead Generation Tool before even starting to build it

Hi, I'm a software developer with an idea for a tool that helps in B2B Lead Generation via Linkedin. The concept is simple, a tool that takes the Linkedin Cookie (Just like Phantom Buster, or DuxSoup, or Dripify, or Expandi, or LinkedinHelper), lets users credit their e-wallet, and use the tool to automate the Lead Generation Process via Schedulers that may be run once, every x duration, or at specific times of the day/week.

The user will be charged on pay as you use model.

The only differentiator I have compared to above-mentioned competitors is the "Ease of Use".
However, to validate my idea even before writing a single line of code, I jumped into Figma to design the basic UI card that will be there in the app.

The idea is that the Users will be given a Canvas for every task (s)he schedule. The canvas can be used with draggable nodes (image attached for reference here https://imgur.com/a/bg8Rac7) and the nodes can be connected via connectors circles. The actionable nodes (the 4 nodes on the right) are the ones without the sub-points. These are the final actions users can take on the entity (entity = "People", "Companies", "Jobs", "Posts", "Conversations", "Comments", "Reactions"). The price is calculated when the actionable nodes are placed in the process

Other features such as setting the filters when searching for an entity can be set using a drawer or a popup when clicked on the specific node. (Just like the way you have it in Sales Navigator).

Is this something that you would like to use?
Also, what else you feel is missing in the tools that are already available in the market?
