So I have tried too make a sword with 100 sharpness using this command

/give @s netherite_sword 1 0 {ench:[{id:16,lvl:5}]}

I seem to be getting an error that says

Line 1, Column 2, Missing '}' or object member name

That's pretty much the only thing I have tried since I'm not great at json, I'm not even sure this is possible on bedrock but I hope it is
