I got a problem when trying to create and send the quotation without confirm trough email to customer. If I confim the quotation, odoo let me to send the confirmation mail to the customer but if I don't confirm it, odoo won't let me to send it. I need to email the quotation to the customer and let it to accept/reject it, not me. Also, if I try to not send it trough email, but trying to copy the link from actions>share, opening the link(on different browser without login in or smth in odoo), when I m trying to accept or reject, it throws me an error. If I accept it, it throw me this error:  The order is not in state requiring customer signature. If I try to reject, it throws me this error:  Your order is not in a state to be rejected. 

I have activated the Online Signature in the quotation and in settings but it does the same. Can anyone help?

The version of odoo I m using:

Odoo 16.0+e (Enterprise Edition)
