I am trying to replace appSetting during release using VSTS Release. All messages on the Internet refer to the old release management tool or refer to the new one, but mention the task of replacing tokens. This task does not exist, so I assume that it is built-in. I installed my web.config ( MyVar ) and set up the environment variables, but did not replace anything.

And here is my release: 
I apologize if I'm stupid, but I just can't solve it, mainly due to outdated documentation.
Update 2: Good, so after some help from a few people, I am now on the right track with this. I added the Colken ALM tokenisation task: https://marketplace.visualstudio.com/items?itemName=colinsalmcorner.colinsalmcorner-buildtasks
However, this will not work.
Here are some screenshots:
Please note that in the screenshot I know that it is disabled. This only happens until I can eliminate it.
In the next screenshot, I see only a few places where you can choose where tokenization occurs. Does this look right or should I see Web.Config in which I want to replace tokens?

As I said, tokenization does not work.
I tried a couple of changes to try to get it to work.
Edit 1: Hover over the zip file above. My release worked, but it did not deploy any of my website files on an Azure server. NONE, generally.
Edit 2: Specify a different CustomerPortal.SetParams.xml file
(Note: at this point I was just trying to use a random file to try to get everything to work) My release worked, but nothing happened regarding tokenization.
Here is part of my journal: 
As you can see, all my files from my site are missing, although the release was successful: 

Any help would be appreciated.
