Instructions

1) I selected and copied the messages from WhatsApp

2) I pasted into VS Code, went to Edit -> Replace, enabled Use Regular Expression, and did a Replace All, using the following search and replacement patterns:

Search for: [\d+/\d+/\d+ \d+:\d+ (A|P)M]\s*

Replace with: \n\n

3) After replacing, select all text and paste into GitLab

That's it!
