Any way to bind Player Move to MB1 instead of MB2?

I've seen old posts from several years ago where you can change some settings by editing the input.ini file in the Config folder of LoL. I tried changing those settings, but they don't seem to do anything (perhaps they do not work anymore?)

The only option I see available in the client is the ability to attack move with left click by ticking a checkbox in the hotkeys section while in-game, but that is not what I am looking for. I am looking for a way to player move with left click instead of right click.

I'm trying to avoid straining my middle finger by right-clicking, so having the option to at least temporarily use left click would be nice. I know its a common thing for mobas and tactical games to use rightclick for player and character movement, but having the option to swap would be great in terms of accessibility.

These were the changes I followed:

Navigate to your config folder and open input (League of Legends/Config/input) Add in the following lines of code:

[GameEvents] evtPlayerMoveClick=[Button 1] evtPlayerSelectClick=[Button 2]

However, when I get into game I am unable to move with MB1 and everything is as normal, like nothing was changed. Upon checking the input.ini the changes are reverted. I have tried setting the input.ini file to read-only. This prevents the numbers from being changed, however I am still unable to move in-game with MB1.

If someone could chime in and help me find a potential workaround I'd be grateful. Thanks.
