Zoom transcript Exceeding character limit. Need to break it into half and store into two seperate fields

I am trying to get zoom transcript and then store it in contentful which has a limit of (50k characters). But the issue is that sometimes when the meeting is long enough it throws an exception since the characters are more than expected. I need a solution like how can I find the length of the transcript and then if it is greater than 50k break it into 2 parts and store in seperate fields. Please check screenshot of the flow.

Is this possible in make.com?
