From CNA:
Pope Leo XIV is now granting apostolic blessings to the faithful around the world, a spiritual gesture that can be officially requested through the Vatican’s Apostolic Almoner’s Office.
These blessings, printed on parchment, are a well-established tradition in the Catholic Church and are available for significant moments in Christian life such as the sacraments of baptism, confirmation, and marriage. As indicated on the website of the Vatican Apostolic Almoner’s Office, the procedure for obtaining an apostolic blessing can be completed in two ways: in person at the offices of this department or through an online form.
