Please help an Alexa newbie!

I have just bought an Echo Show but I think I had overestimated the abilities. For example, I wanted to be able to search Spotify visually, using the screen as per the screenshot from my phone. However, all I can do is activate Spotify verbally, which is what I wanted to avoid! Have I totally misunderstood the point of this?
If so, could I connect an old iPad using an Aux to stream music into the Echo show speakers? I could connect my Bluetooth but that isn't always reliable.

Sorry to be so daft!

You set up Spotify in your skills and then control from your phone?

See if it's recognised as a speaker on Bluetooth

But then there is no advantage to having a screen, is there?

I only have the Google one. You set it up in the Home app, set Spotify as your music app, and I just tell Spotify what to play. I can also change the song on my Spotify app and it continues to play. I would have thought they're all similar

@JangledBat : but that's the bit I'm struggling with, telling it what to play! I sometimes need to browse and I thought the screen would facilitate that?

I'd try Googling or look in their FAQ then

I have, but haven't found answers. I just hoped a more experienced user might be able to help me out.
Thanks anyway.
