When expanded, how to show the collapse button below

hi, I am working on a profile page. and I need to use this plugin for the bio where if the bio is long, the bio will be expandable. But the issue is that when I press the read more button, but read more button will stay there. So, how can I have the functionality like https://haas.berkeley.edu/faculty/david-a-aaker/?
When I press on read more, it will change the text to collapse and move it downwards

Thanks
