Is suffixing an invitation with “if you want” a bad thing?

Let’s imagine a couple scenarios in maybe a pub or social situation.

Someone I know comes up to say hi and I say hi and then say “have a seat if you want”, is it a bad thing to say “if you want”, as in it discounting the invitation I’m giving for them to come sit with me or is it seen as a polite gesture that implies I’m not forcing them to?

I get to know someone and find them interesting, let’s say they share the same passion for my main interest. I’m interested in staying in touch and making a friend. I offer my social media and I say “here’s my social media if you want it”. Once again is this discounting the offer or a polite gesture.
