About Search Console! Help

[panduh]

I noticed in Search Console that a total of 22 of my pages are in the 'discovered - not indexed' category, and 18 pages are in the 'crawled - not indexed yet' category. In total, 40 of my articles are not indexed, some of which were written two months ago. Now my question to experienced friends is whether there is anything I need to do? From what I have researched online, it has been mentioned that the reason may be related to duplicate content, but my articles are completely original. What can I do to get these articles indexed? I would appreciate your help.
