However, we could use the "allow channel administration" permission to allow you to share control of the lvee2017 channel. It would be a good test of that feature, which I do not have experience with.

Is it correct, that "allow channel administration" permission will be permitted in this dialogue - s. Screenshot (Hubzilla Version 2.4RC)

But I find this option not. How can I activate the "allow channel administration" permission to allow for one Hubzilla Hub member to share control of one channel?

No, the setting is in the individual connection permissions settings.

Edit Connection -> Individual Permissions -> Can administer my channel

If granted this permission, you can use the channel manager to find this channel added to the list of channels you own, but it will be listed as a Delegated Channel. You click the link and are effectively authenticated as that channel and can edit that channel's content and make posts, etc.
