Add "read more" option

I’m looking for an option to add “read more” button or link to expandable text.
I already tried <!–more–> in text widget and in SiteOriginEditor, but with no success.
In following example -
text1
<!–more–>
text2
text3

I see -
text1

text2
text3

Hello there,

I would like to apologize in advance for responding slowly.

As far as I know, the more tag <!-- more --> only works with the regular post/page content editor. It won’t work with the page builder editor.

As an alternative solution, try to use the Expander plugin.

Regards,
Kharis
