Are the ext-sms-providers & Elbasoft both supposed to be installed to integrate SMS?

I first tried installing the ext-sms-providers extension from the official github, and later on we installed Elbasoft because we wanted to use the features it has to offer, like mass sms sending. However, I've been having difficulties setting up sms in the first place because Bandwidth is not one of the officially supported providers in the providers extension. I did make custom files mimicking the process the other providers follow, and I am now able to select Bandwidth as an option as well as enter necessary credentials, but I have not been successful at sending an SMS message so far, and I am not sure how to go about setting that up. Bandwidth has an inbound and outbound urls needed to work, but I don't know what those would be in relation to espocrm, and I'm worried Elbasoft might be conflicting with something

Elbasoft is third party.

SMS extension is 'official'
