Script to change specify text style within Google Sheet's cells, but I cant seem to style text manually [closed]

I have this script in Google Sheets which find keywords that highlight them for me in the cell. But I also realize, i can no longer do manual text styling within the cells, they get reset to the cell style because the script also reset cell to undo the automative styling when the keywords are removed.

Is it possible to achieve both options?

1. Automative styling and unstyling of keywords when they are typed in (currently working)
2. Allow manual text styling to other text that are not indicated as keywords

Here the google sheet i am working on: LinkCredits: Script originated from here
