Temporary User access for Kwikset 910 lock?

I have just newly started with Smartthings Hub v3. I am coming from Iris.
I have paired a Kwikset 910 zwave lock.
I can’t seem to figure out how to set temporary access to the lock, say for a sitter or whatever. I am reading on this forum and I am thinking this is possible which I can’t believe that there isn’t a way to do this in the app.
Anyone know how or is that the one good thing about the soon to be defunct Iris Platform that I am going to miss.
I have figured out how to set up a user code for the lock but I only see option to be live or delete the person.
Please tell me I am missing something.

There is a paid app…
