My email name is different

Hi Zoho, Please help me, I tried to connect my domain to zoho to create a business mail, I have connected the MX and the SPF, but I can't see the DKIM. Please help, I tried to send an email and the email address that is appearing is 1654898292707_781532065@zohomail.com

I also tried to delete the Domain name (Yet to point MX records) to redo the process but I can't erase it saying it is the wrong password huhu,

I am so desperate please help me.
