CODESYS KNX SL with ETS6

Hi all,

I have a KNX System running in my house and I wanted to use a CODESYS PLC to interact with my KNX System.
The problem is that I am unable to import the exported ETS configuration file from CODESYS (XML file) into my ETS6 project.

The CODESYS KNX SL product page states ETS5 and CODESYS DCA for ETS5 as preliminaries, but according to the Codesys Sales Support (answer asked through Codesys support ticket), the ETS configuration can be imported into ETS6 the same way as in ETS5.
The support further told me that the following instructions also apply for ETS6:
https://content.helpme-codesys.com/en/CODESYS%20KNX/_knx_ets5_plugin.html
I could not follow it, because Step 4 of the guideline cannot be done. I could not find any option to insert a XML ETS Configuration through the Codesys DCA.
Unfortunately, I only started this year with ETS and had no other choice than buying an ETS6 license.

About my Setup:
1.) KNX System programmed with ETS6 Home 6.4.1 (Build 8718)
2.) DcaCodeSys Version 1.0.0.0 installed in ETS6
3.) MDT SCN-IP100.03 IP Router installed for connecting KNX Bus with Ethernet network
4.) CODESYS based RevPI PLC with CODESYS V3.4 SP17 Patch 4 running
5.) CODESYS KNX SL installed

The question is how to import the XML, because I cannot find any CODESYS based devices to insert first, before the DCA from Codesys can work. (As I understand how the XML needs to be imported to ETS).
Any information available, how I can connect/prepare a CODESYS PLC with ETS6?

Thank you for your support!

BR
