Hello Aurelien,

Thank you for getting in touch.

You can change strings in the plugin by using the translation method, but in your case you would change strings in the same language, you wouldn't translate them to another one. 

Strings can be changed using POEDIT or Loco Translate for example. If you want to use POEDIT then this is the instruction:

1. Download Amelia from TMS Store

2. Unzip the downloaded file.

3. Download and install POEDIT. 

4. Open the program and open the file from the extracted folder on your computer ameliabooking/languages/en_US/wpamelia-en_US.po.

5. Change the strings you want.

6. Save the translation.

7. Go to ameliabooking/languages/en_US/ folder and copy these two files - wpamelia-en_US.po and wpamelia-en_US.mo back to your website to the location ../wp-content/plugins/ameliabooking/languages/en_US/.

Please note that this change would be overridden when you update Amelia, so you would need to apply it after each update of the plugin. 

Regarding have a variety of services, such as, zoom classroom, video lesson, chat session

you can create services with these names in Amelia, if this what you want to achieve. You can also create more categories if that would help. https://wpamelia.com/services-and-categories/
