Microsoft 365 distribution group, 'send as' permission

I have created a distribution group in Microsoft 365 and added users to it. When I want to send as this group and select this group in the 'From' button in my new message and send it, I get an error saying:
*This message could not be sent. You do not have the permission to send the message on behalf of the specified user. *

How can set the 'send as' permission for a distribution group in Microsoft 365?

    Tried everything from here and others, for me helped to changed owner and change it back to me. It started to work when I changed owner from me to other user. So I tried if it's problem of same owner and user or something. But wasn't able to replicate the problem with other DL. So I changed the owner back to me and it stayed working.

    When creating the DG, do the people who need send as also need to be members?? You go in and add them as members when the group is created and then have to go in again and give them send as??
