Discord js Shop Roles?

Question

JavaScript

Good morning, I want to write a role store with the ability to set its price and its role using the shop add command, but I have no idea where to write the values ​​from the command so that it later displays them in embed, there are suggestions, maybe options, I will be glad any help.

For example:
set add @Role 15000
Creates/edits addFields by setting name: @Role
value: 15000

If the user adds a new role, creates/edits another addFields
