label written on top of the header

hello
i have overwritten a part of the luks2 header with an mbr label but the 2nd binary header and 2nd json area and everything after it is fully intact
i am coming back to this after a long long break because when i saw "By far the most questions on the cryptsetup mailing list are from people that managed to damage the start of their LUKS partitions, i.e. the LUKS header. In most cases, there is nothing that can be done to help these poor souls recover their data." i decided to give up
but now i decided to do some more digging and it seems to me that it is recoverable

i created a new volume with the same settings to see how it should look like and then on a copy of the original drive i changed the starting part to be the same as the one from the new volume (the LUKS ... @ ... sha256 ...) and the rest from the 2nd binary header and 2nd json in the place where the 1st ones should be using hexedit and then that looked like a normal working luks header

but that didnt work, so now im here
if the command is:
cryptsetup luksOpen <device> <name>
then does the <name> matter in decryption? or can it be anything? because if it cant be anything then i dont remember it nor have access to it after such a long time

also after creating a few sample volumes i have noticed that the area where the 1st binary header and 1st json area are compared to the area where the 2nd binary header and 2nd json area are is not identical because there is some undocumented something, unspecified in the https://gitlab.com/cryptsetup/LUKS2-docs/blob/main/luks2_doc_wip.pdf , if its not random then it was overwritten by the label

and the last thing i can think of, does the uuid of the device matter in decryption?

im sorry for bothering but please tell me what to do, if anything can be done
