Filament Change on Mega S

[HowSway26 0]

Just bought my Mega S and I have made many projects but now I am in the process of trying filament changes to up my skill level with dynamic prints. The issues I am having is while using using Cura 4.13.1 and I utilize the 'Filament Change ' script (where the print completes without pausing at layer chosen and the layers start to shift near the end ) and the 'Pause at Height' script (where the print did pause but there was no option to do a filament change). I have searched throughout various forums to find a solution but many answers are from 2018 and it seems Cura has changed a lot since. So, I am not sure what avenue to follow besides the last step which is trying to mess with Octoprint to get intended results.

Does anyone else have the same issues and if so what solutions are available to start making color changes with different filaments.
