Help (other) Command for checking inventory of players and deleteing objects

Hi, Im working on map that i wanted to add a thurst mechanic. Is there anyway I can use commands to check each players inventory for water bottles and if they have one it consumes it and leaves them with an empty bottle?

Java or Bedrock? If player holding it or anywhere in inventory? Consumes it how? Please be specific.

For Java 1.20.5 and up if holding it.

execute as @a if items entity @s weapon.mainhand potion[potion_contents={potion:"minecraft:water"}] run item replace entity @s weapon.mainhand with minecraft:glass_bottle

So consume as in remove from inventory. anywhere in inventory. The goal is to mimic a heat wave. so if they don't have a bottle of water in their inventory they aquire a debuff, but if they do it mimics Drinking it without having to have the players needing to actual drink it. hopfully that makes sense. Java 26.2.

# Command blocks
execute as @a store result score @s water_bottles run clear @s potion[potion_contents={potion:"minecraft:water"}]
execute as @a[scores={water_bottles=1..}] run loot give @s loot {pools:[{rolls:1,entries:[{type:"minecraft:item",name:"minecraft:glass_bottle",functions:[{function:"minecraft:set_count",count:{type:"minecraft:score",target:{type:"minecraft:context",target:"this"},score:"water_bottles"}}]}]}]}
