Validity of guest invitation to Poland

Hello,

I received a guest invitation from my friend in this year. The invitation is valid from 01-02-2024 till 31-08-2024. I already got one visa for three weeks in February/March 2024. Can I re-use this invitation to apply for new visa to visit Poland again in summer 2024 (till 31-08-2024). Or for each visa I should get new invitation?

Thank you.

I think as long as the invitation is valid, you may be able to apply for new visa with it (ask legal sources though or the Polish embassy).
