Where do I find my vault on mobile? How to create a button with a function on android?

Hi,
new to logseq. Somehow I cannot figure out where my vault is saved on android or how change settings to move it?

And another question I have is, how is it possible to create sime of the little custom square buttons like in the toolbar aboce the keyboard myself. I would like to have some custom functions like for advanced clozes, formatting, quickly setting tags etc… that I can quickly call. I am using android. Or what is the quickest way to do an action? Preferably lowest amount of steps with potential for complete automation.

Btw does anybody have experience in using voice control with logseq. I am interested in using a mix out of tasker with chatgpt and logseq…

To see where the graph is located, click on hamburger menu, then on “Logseq” dropdown, then an “All graphs” and you should have “Open a local directory” button, which will open its location. Moving it has to be done outside of LogSeq, I guess. Just move the files into a new location, add this location as a new graph and unlink the old one.
