I'm currently working on understanding the process for establishing an HRMP channel between a parachain and the [Rococo Asset Hub] (Rockmine).
I'm wondering whether a motion to the governance is required, similar to what would be done for Polkadot/Kusama, in order to initiate the HRMP channel. This would involve signing the
polkadotXcm.send extrinsic containing the encoded call of
hrmp.hrmpAcceptOpenChannel for incoming handshakes and
hrmp.initOpenChannel for outgoing handshakes with root origin. Alternatively, is it necessary for someone with root access to perform this action on my behalf? I came across https://github.com/paritytech/subport for similar queries, but I'm uncertain if it's the appropriate resource to submit such an issue.
I attempted to find information about this question in the Polkadot Wiki, Substrate Wiki, and here, but unfortunately, I haven't come across anything relevant. In the event that there isn't existing documentation, I plan to open an issue in the Substrate docs repository, with the intention of eventually incorporating the provided guidance into the official documentation.
