intermediation between 2 users directly

[VGCif]

Is your feature request related to a problem? Please describe.
2 users may want to use the brokerage of the bot to make payments-exchanges between them directly without posting their offer to the others

Describe the solution you'd like
It would be necessary to enable, apart from the general group and the community group, a function in the private channel with the bot of the type: "intermediation between 2 users", where the bot acts as insurance for an exchange. where you would put the name of the user to whom it is intended, in the generation of the order

Describe alternatives you've considered
could, instead of being a new command, use the same "publish order" command but with one more parameter: "concrete user"

How about this?

• Alice creates an "unpublished" order (does not appear on any channel).
• Alices gives orderId to Bob by whatever method they want (tg, wsp, etc)
• Bob executes /takeorder <AliceOrderId> (Add /takeorder command #371)

How about this?

* Alice creates an "unpublished" order (does not appear on any channel).

* Alices gives `orderId` to Bob by whatever method they want (tg, wsp, etc)

* Bob executes `/takeorder <AliceOrderId>` ([Add /takeorder command #371](https://github.com/lnp2pBot/bot/issues/371))

this sounds good, simple to code and easy to understand to users
