What can I change in the Android settings so I am able to have a particular virtual number app to be shown as one of the options when I try to call a customer from a food delivery driver app? I make occasional deliveries for Doordash and Grubhub. I use a virtual number (instead of my real phone number) with my accounts with them. With Grubhub I use Textplus app and with Doordash I use Second Line app. I would like to be able to have those apps as options whenever I try to call/ text a DH/ GH customer from their apps. It usually gives me an option of apps I can use to text/ call a customer from a current order, but not those two. Here is a 30 sec video showing the apps that come up when I try to do it from Doordash. I just uploaded it to show to you: Do you guys know what I can change in the settings for this? Thanks in advance
