Hi @meikedewith
The DEX library intentionally does not expose the access key of the ADLS account, as these provide the keys to the kingdom. Instead you can use the Datalake Tools AIMMS app, to create a SAS token that you can use to provide access to the ADLS account.
I've just updated the datalake-tools repo for the Datalake Tools to become a little bit more intuitive in it's use. You can clone the repo, and publish the app in the cloud account for which you want to create SAS tokens to access its assoiciated ADLS account.
With the app you can create Account SAS tokens (giving you access to the account and any container in it), as well as Container SAS tokens (giving you more fine-grained access to just a single container), and it also lets you create or delete containers (i.e. file systems) within the ADLS account.
My advise would be to create a new or select an existing container where you want to read/write, and create a long-lived SAS token that you can use for accessing the ADLS account from your desktop. How to set this up is described in https://documentation.aimms.com/dataexchange/dls.html#authorization.
Please make sure that you don't store the files in api-init to your git repo.
