Namaste.
I wish I was a tech and could tell you how to do that.... But that is something I am trying to figure out too. Sometimes I get lucky and can do it...
Check out "learn to code" it is a online course designed to teach kids ... K-12...And has a lot of course web building - app building included in it . And since it starts for little kids it is easy to progress thru. I am getting better at this stuff....Lol...Thanks to them.
