There is a feature in game chat, when one kills other it's show the weapon used to kill. I expect, it's should be possible to hover over weapon name to see the tooltip with item description, as how it works on other Minecraft servers.
However, instead of tooltip I getting small error spam in the log every time someone killing other, like this:
[03:06:18] [Netty Client IO #5/WARN]: Failed to parse item tag: literal{{"id":"minecraft:bow","tag":"{Damage:47,Enchantments:[{id:\"minecraft:infinity\",lvl:1s},{id:\"minecraft:power\",lvl:4s},{id:\"minecraft:punch\",lvl:2s},{id:\"minecraft:unbreaking\",lvl:3s}],RepairCost:3,display:{Name:\u0027{\"text\":\"POW POW SKRR\"}\u0027}}"}}[style={}]
com.mojang.brigadier.exceptions.CommandSyntaxException: Invalid escape sequence '\u' in quoted string at position 219: ...ay:{Name:\<--[HERE]
I am not sure, but it seems, due to incorrect escaping item info can not be parsed and shown in chat.
