How do I withdraw from Coinomi?

Could you please explain the process of withdrawing funds from Coinomi in a step-by-step manner? Are there any specific requirements or precautions I should be aware of before initiating the withdrawal? Additionally, what are the potential fees associated with withdrawing from Coinomi, and how can I minimize them? Lastly, is there a limit to the amount of funds I can withdraw at once, and if so, what is it? Thank you for your assistance.
