The Licensing Website is the place where organisations can access their Adobe license information, serial numbers and ESD downloads.
Each organisation has contacts attached. Only these named contacts can access LWS.
The usual process would be to ask the existing contact(s) for your organisation to provide you with access to LWS.
For further details see Adobe Licensing Website | Serial numbers, orders, and accounts
If you don't know who that is, or if they have left your organisation you should reach out to Adobe support for assistance (details below) - if you have trouble feel free to ping me via a DM here and I can check that for you.
Creative Cloud for Enterprise - from the Admin Console go to the support tab to open a case. Phone and chat options are also available here.
Creative Cloud for Teams - from the CCT Admin Console go to the Help tab for chat and phone options.
