This motion will trigger a Transact message on Polkadot to send an HRMP request to Polkadex.
The transact will be performed on Polkadot with the following call:
0x3c00f8070000e803000000900100
which can be decoded as:
hrmp.hrmpInitOpenChannel(
recipient: 2,040
proposedMaxCapacity: 1,000
proposedMaxMessageSize: 102,400
)
Phala's sovereign account has already got the enough deposit to open the channels.
