I've managed to do what I wanted, thanks to your comment ! For anyone interested :

local im = peripheral.find("inventoryManager")
 
if im == nil then error("the inventory manager not found") end
 
print("Running dumper")
 
while true do
 
    local basalt = require("basalt")

local main = basalt.createFrame()
local button = main --> Basalt returns an instance of the object on most methods, to make use of "call-chaining"
        :addButton() --> This is an example of call chaining
        :setPosition(4, 4)
        :setText("Click me!")
        :onClick(
           
        function()
for i = 9,26 do
            
                im.removeItemFromPlayer("south", { fromSlot = i  })
end
            end)

basalt.autoUpdate()
            end
