is there any auto-completion?

Before MC 1.20.5, I was returning my items with string tag "OzelEsya" of nbt of player's held item expression.

My question is, am I have to do add minecraft:custom_data; to beginning of the string every single time in newer MC versions?

I can get OzelEsya data still using string tag "minecraft:custom_data;OzelEsya" of nbt of player's held item but string is unnecessarily(?) longer than usual.

check tag:

full nbt (not complete):

nbt (not complete):

---

When I use #set string tag "OzelEsya" of nbt of held item to "Oyun_Kiran" nothing happened on the item, so I added this string to custom data with #set string tag "minecraft:custom_data;OzelEsya" of nbt of held item to "Oyun_Kiran".

every single SkBee update since 1.20.5 has been released, has included details of the changes to how SkBee handles NBT.
There is also a link to a wiki in those posts that further explains in greater detail all the changes and what you will need to do on your end.
I recommend reading those changelogs and wikis.
