How can i turn my drop item script from a "touched" to a proximity prompt activation?

I have been trying to make a proximity prompt on a part where it puts the tool you have in your hand to a different part's position for my shop game. I finally got it working but it is a "touched" function, not a proximity prompt. I've tried changing it and looking for other scripts but this is where i am. Please ignore the "door" and that, it's just what the tutorial had it called ????.

Touched part script:

local door = script.Parent
local ToolSpot = script.Parent.Parent.ToolSpot

local function remove(otherPart)
    local humanoid = otherPart.Parent:FindFirstChild('Humanoid')
    local player = game.Players:FindFirstChild(otherPart.Parent.Name)
    if humanoid and player then
        local inHand = otherPart.Parent:FindFirstChildWhichIsA('Tool')
        if inHand then
            inHand.Parent = game.Workspace
            inHand.Handle.Position = ToolSpot.Position
        end
    end
end
door.Touched:Connect(remove)
