Installing module but not listing in admin

Hello everyone,

I am trying to install a module. I am following all the instructions in

After entering composer require tabsl/tabslsets
It does not install module in module folder instead it install a folder in vendor folder with just composer and file.
How can I solve this?

Which version of this module die you buy, v4 Pro or v3?

i bought v3 version,
They sent me the wrong version for oxid 6.

Now they have sent me the right version for 4.10.2 and I am trying to install manually
