Can I safely get through E-gate when entering the UK after being given code 3 landing?

I'm from a non-visa national country.

I'm planning to visit the UK for 3 weeks or a month for just travelling.

However, I am seriously concerned about whether I can enter the UK with no trouble due to my troublesome immigration history which happened in January 2019.

So here are my full detailed history of visiting or staying in the UK

In 2015, from June to December, I stayed as a short term student visa for 6 months In August 2016, I stayed for a month as a visitor.

In September 2017 to January 2019, I stayed for 1 year and four months to study my masters on a Tier 4 visa.

so what happened earlier this year, when my student visa was almost about to expire, I was not ready to go back to my country for some reasons so I just went to Paris for a few days and came back to the UK right after my student visa expires.

I was seeking for a standard 6 months visitor visa, but the IO was suspicious of me and said to me that "You shouldn't be doing this." Probably the IO was suspicious that I was attempting to take advantage of the visa rule as a non-visa national, in my opinion.

The IO asked me when I intended to leave the UK and I told her that I only needed a week. Then she asked me to show the return flight ticket, which I prepared. After she looked at my return flight ticket, she told me that she would write the exit date I told her on my passport and warned that staying more than one week would make me an illegal stayer. That's when I was given 3 code landing. I got 3 letters and five numbers with the date written on the stamp. The IO ended up letting me in the UK but I failed to get a 6month visitor stamp.

I left the UK exactly the designated date as the IO told me to do so and I'm in my country for almost 10 months now. I also have a job here.

In December 2019 or January 2020, I am planning to visit the UK again as a holiday to see some of my uni friends and travel northern England for at least 3 weeks.

In May, The Home Office announced that people from several selected countries are able to use E-gates from mid-May 2019 and no need to write the landing card nor facing the IOs. My country is also one of those countries, however my concern is that I am pretty sure that I've been flagged due to the struggles with the IO which happened in January this year. Can a person like me who's got 3 code landing which implies negative immigration history use E gates without any problems?

I seriously don't want to face the IO and don't want to be interrogated or worse detained because of my coded landing history when I go back to the UK the next time.

I tried to search for some relevant posts but there are no posts about people using E-gate after being given coded landing or after experiencing troublesome immigration getting through.

I look forward to hearing helpful comments.

Update: I arrived in London on the 28th January and I was successful passing the eGates!
