All of your Machiavellian scheming is done via PMs to the other players.
However, once you arrive at any formal arrangement, i.e., any actual change of diplomatic status results from your discussions, you must inform France (who clicks all the buttons at the beginning of the round), by declaring it on the board here in turn order.
For example, because France goes first diplomatically, Moilami must to announce any changes of status that involve him, and then pass to the rest of us in turn (as that’s the order the buttons have to be pushed), which means UK declares second, and so forth.
Thus: I will announce on Moilami’s behalf that France and Austria have, after lengthy and pained negotiations, arrived at a ceasefire.
Moilami, do you have anything more to add diplomacy-wise before Degrasse makes his political declarations (if any)?
