I’m working with ABP framework + Angular (UI) commercial version

So, on the tenants module, we can create tenants, and those tenants have features as explained here:
https://docs.abp.io/en/abp/latest/Modules/Feature-Management

Well, I want to add a new feature to this module. The docs say that I should create a service for that, but which layer of the project should I create it on? How should I make it? Did someone have an example of how to do that?

What’s the purpose of this: hide or unhide a menu item on the Angular UI of the selected tenant if the new checkbox inside the new feature is turned on or off

As I can understand, there are 3 feature tables.

• AbpFeatures
• AbpFeatureGroups
• AbpFeatureValues

But how can I populate them with new data? Is it doing manual insert on the database?

I appreciate any help you can provide an example step by step on how to achieve this.

Thank you in advance!
