A word/word phrase meaning 'a tiny detail'/'a small thing"

I am looking for a word/word phrase native English speakers use as an expression for 'a tiny detail' / 'a small thing' (when mentioning something but adding that it is not so important). I came across the word 'a trifle' but am not familiar if and when it is used in this meaning. Do you say - 'such a trifle'?

Example: Such a tiny detail/such a small thing - I wish there was a night lamp in the room.

Thank you in advance!

no biggie (Cambridge Dictionary)

used to say that something is not a serious problem:

I was a little disappointed that they don't serve brunch on Saturdays, but hey, no biggie.

Using no biggie in the example sentence (It's being optional):

(It's) no biggie, but I wish there was a night lamp in the room.

Merriam-Webster lists no biggie as an idiom (informal, with or without it's).

Another simple definition and example of the phrase no biggie (Lexico.com):

Used to indicate that something is of little consequence.

‘no biggie, I'm not in a hurry’

You could also say "no big deal." Lexico.com gives the same defintion for it.
