Phone by Google - How to back up contacts?

[Malevolence]

I use the above app for my phone dialler and am getting a new phone today. For the life of me I cannot find any option in said app's settings to back-up or sync all my contacts. I really don't want to go through and have to manually add God knows how many entries.

Am I missing something that's staring me in the face?

Tried that, the Contacts for my Google account is empty despite them being on my phone and under the same account. So can't back them up as there's nothing there to back-up. Only showing on my phone, and in the app. there is no option to back-up/export.

Only managed to sort it out today. **** knows what the issue was. Yesterday I installed it on my new phone and it was showing no entries despite me using them on a daily basis. So uninstalled contacts from the new phone and checked online via my PC (and my old phone) and all my contacts were present and correct. Reinstalled contacts on my new phone and nothing, it was empty. Tried a few more times and on about the third try my contacts were present.

Guessing it was a glitch somewhere within the Google ecosystem.
