This feature will be introduced in Live in an upcoming patch. You can give it a go on TestLive right now.
KNOWN ISSUES
Due to something with the way the launcher is set up in the depot, the launcher is skipped upon launching. Developers are working to resolve the issue.
Just for the record, steam downloaded a TestLive patch for me but I don’t have any launcher, the folder is not where it used to be last time we tested it either. Verifying TestLive files didn’t find anything.
EDIT: Uninstalled TestLive and deleted any left over folders. After fresh download and install from scratch, still no launcher folder/exe.
I also determined there were no files named FuncomLauncher.exe within the path *Steam\steamapps\common\Conan Exiles - Testlive Client*, and agree that @Ignasi is aware of it.
