How do I indent all endnotes except for endnote character?

The default endnote style has the following indentation settings to allow for there to be a gap between the endnote character and the endnote content:
Before text: 0.60cm
After text: 0.00cm
First line: -0.60cm

The problem with this however, is that new paragraphs within the same endnote begin at the same place as the endnote character, instead of the rest of the endnote content.

I would like the endnote character to remain at a distance from the endnote content, but I would like endnote content paragraphs to be indented equally. How do I do this?

For second and subsequent paragraphs of the note, just press Tab on the first line. This will align text of “Before text”.

When you request negative first line indent, this implicitly created a tab stop on left indent, aka. “Before text”.
