armory redeem item with stars

[santigo]

how to use node-globaloffensive to execute the command and protocol for redeeming items with Stars in the CS2 Armory?

i guess the command like this:

k_EMsgGCCStrike15_v2_ClientRedeemMissionReward = 9209;

and the protocol like this:

message CMsgGCCstrike15_v2_ClientRedeemMissionReward {

    optional uint32 campaign_id = 1;

    optional uint32 redeem_id = 2;

    optional uint32 redeemable_balance = 3;

    optional uint32 expected_cost = 4;

    optional int32 bid_control = 5;

}

but i don't know what's the param's value

i can parse redeem_balance from hello，the type id is 6 and the protocol like this:

message CSOAccountXpShop {

    optional uint32 generation_time = 1;

    optional uint32 redeemable_balance = 2;

    repeated uint32 xp_tracks = 3;

}
