I have the .csv file, which includes the direct URLs to the images in the columns. Unfortunately, I can't open them at some point.

I was unsuccessful, as I noticed an utter lack of reaction when clicking on my layer. Moreover I couldn't see the "Action" column in my data attribute table. I use QGIS 3.12 version.
Next I thought, that potentially my widget was wrong, as indicated in this thread:
How to use hyperlink for image popup in web map based on QGIS 3.4.3?
Show images related to features in QGIS?
but it didn't change after choosing the "Attachment" instead of "Text".
How can I make my image popup valid? What I am missing here?
UPDATE:
This hint
Using Hyperlink URL in attribute table of QGIS?
also didn't work for me
