[twitter-dev] visiblitiy of @mentions in Tweets

[MuratMetu]

Hello, I am new to Twitter development, I want to know  is it possible
to change visibility of mentions in my tweets.
I want to mention somebody via @username in my Tweet x, but also I
want Tweet x to be visible only for the user spesificed with username.
I don't want to use direct message since as far as I know there
should be at least one of the 'followed'  or 'following' relation in
order to send direct message.  Thank you.
