Hello! It depends on how you agreed at that time, whether it was an exclusive license or a partial license.

If you originally agreed on an exclusive license, only you have the right to use the trademark, and the licensor and others can no longer use the trademark, then you can authorize others to use it. If part of the license is agreed, not only you can use it, but also the licensor and a third person can use it, then you have no right to authorize others to use it.
