Updating Picker Items Dynamically in UXP

I have a picker (formally a dropdown) made with this:

		<sp-picker disabled id="sp-login-tab-page-domain-picker" placeholder="">
			<sp-menu slot="options">
				<sp-menu-item value="0">Not Logged In</sp-menu-item>

I want my UXP code to edit/change/add/delete the menu items. I don’t In the UXP debugger, I don’t any methods. Does anyone have any samples or tips?
