The date printed on the stamp is for 2019. I only have a 2014 catalogue, but maybe someone with a newer issue can give you a number.
Colnect suggests this is Michel BL45 / Yvert et Tellier F2163 (no Scott or SG numbers yet) issued on 3rd December 2019.
Stampworldcatalog.com shows it as issued December 23, 2019, but no Scott number of course. Value shown is 1.33 Euros.

Scott number is 1532. The 2022 Scott catalog lists it at $1.75 Mint or Used.
