hello! firstly thanks for all of your hardwork! second ofcourse you can I dont understand why you would ask me for permission.
Since it's your first time TL-ing you might not know this.
This is just a general guideline, but it is considered a bad practice to TL and upload a series that has an active translator. It's called sniping. Generally, before you do that, you'd ask the original translator first so not to waste their effort (they might be in the process of translating that chapter). It is highly discouraging to actively work on something only to find out someone already did it.
As you may know from having worked on it yourself, translating a manga is a lot of work, and sometimes life get in the way and the release schedule may be delayed, but that doesn't mean they have stopped working on it. Unless it is unusually long (generally 3-6 months) it's always a safe practice to ask the original translator first before you do the sniping. And in this case zanas last upload wasn't even a month old.
