Bug - Cannot use ABFS file connection to load data in KQL database

On the storage-connection-strings  page, it is stated that ABFS connection strings can be used, with a connection to ADLS Gen1 and Gen2.

However, when trying to use this connection to load data to a KQL database, I am getting an error saying that I need to enter a valid OneLake path, like https://
I initially thought that I needed to use another source type, something specific to ADLS, but the only Lake option is the OneLake.

The file itself is stored in a Lakehouse in the same workspace. The connection string was copied from the Proprietes pane.

Using the URL string instead of the ABFS one will work, but I want to know why the ABFS one isn´t working.

Is this a tool bug or do I need to configure something to be able to access this funcionality?
