Perhaps there is only one possibility: to speak at a meeting of the academic council of your scientific institute with a statement on the approval of your authorship and sending a letter to the editor of the journal about your inclusion in the authors of the article. The presentation should be strictly justified: what scientific contribution did you make to the article (proposed a research project, conducted experiments, made calculations, wrote a text, etc.). Find defenders who will support you at the meeting of the scientific council.
The first thing to do is to verify that you should be an author. The generally accepted criteria are the ICJME criteria (also known as the Vancouver criteria) which are available here: http://www.icmje.org/recommendations/browse/roles-and-responsibilities/defining-the-role-of-authors-and-contributors.html
There is a very helpful finnish page that discusses authorship here : https://vastuullinentiede.fi/en/publishing/who-qualifies-author-research-publication
If the paper is submitted and under review, you can write in confidence to the journal editor. If it is published, you can complain to the research committee or equivalent body in your institution that has oversight of professionalism issues.
Early in my career I too was at the receiving end of this sort of behaviour. In fact, one researcher made me sign a statement to say that I made no material contribution to the research, despite working on it for three years! At the time, the choice was between having a job and not having a job. Nowadays, professionalism is taken more seriously, and you can and should demand your rights as an author.
