I have many links from a permanently offline/down instance of Lemmy (closure announcement #1 , #2 ) like:

https://lemmings.world/post/10000001

https://lemmings.world/post/10000002

so how do i convert these links so it links to a federated (backup) content on other Lemmy instance/s?

Is my only chance to try https://web.archive.org/web/*/https://lemmings.world/post/10000001 to find out post content/name, so i can use search engine to search that post name if it indexes federated version of the original post?

If i know the post name, do i have better way to find the federated content address beside using internet search engine?

It seems like Lemmy sucks (still too centralized), possibly similarly to https://spasm.network/apps (i am yet to try its federated forums).
