How to add custom links in footer

Hi, I’m using Activello theme for my webshop (with woocommerce) and have been very successful so far.
Only thing is I need to add one or two links leading to my “terms and conditions” pages in the footer.

I have removed the original text and added my own but how can I add a link?
Also, but not as important, is there any way to have more than one line for text in the footer?

Will I have to use a child theme? Never used one before… If I install one, will that make changes to the design and setup I have now? Thanks a lot!

I have found a solution via child theme in another thread. Thank you

Awesome great to see you got the solution found.

Please advise if you have more questions.

Have a fantastic day!
