HL7 file import to procedure electronic reports

I followed the procedure in the following post, of several years ago:

It does not work for me, and I have tried many iterations of different file permissions, ownership, location. The file will import directly into a patient’s page, but it will not show up in the electronic report area.

Is this a working function? After 5 years since the referenced post, it may just not be possible. I see very little, if any, posts on HL7 data import. This is simply a test from a local file. Not even trying to connect to a device at this point.
