Connect Minecraft plugins spigot and bungee cord?

Short question:

Is there a way that a spigot plugin can communicate with a bungee cord plugin?

(I plan to make a ban system. However, I would like to do it using an inventory and you can't make an inventory using bungee cord)

Of course there's an integrated solution: https://www.spigotmc.org/...g-channel/

Depending on the application, this can also be done differently. Bans could be stored in a SQL database, for example. For simple communication between processes, on the other hand, Redis is more powerful than plug-in channels and significantly more functions are supported.
