Overstayed number of days by 2 days - will this impact next application?

I applied and got a visa during the west asia crisis peak - I was travelling from the UK. The visa was valid for a month, but period of stay was 5 days. I missed this as the consulate stamp was on the number and I wasn’t aware of this concept as this was my first time applying for a visa.

Long story short due to travel concerns of family travelling with me, I ended up pushing my flight to the UK by 2 days ; so I stayed a total of 7 days in the Schengen area.

I will be applying for a visa again soon and was wondering if this will impact the application. Should i voluntarily explain the context in a cover letter or is that not required? For context, I was not stopped at the immigration at my exit point during the last period - it went very smoothly and hence I have only realised this issue now.

Thanks in advance!
