I know how to locate div inside the button:
//button/div[contains(text(),'Save')]
I'd like to know is it possible to locate any button which contains div with text "Save" inside?

<button class="PinBetterSave__Button" data-test-id="PinBetterSaveButton"><div class="_w7 _0 _1 _2 _wa _36 _d _b _6">Save</div></button>
