Select the access policy and language.
Select Common Page Styles
Select the logo from Header logo section.
Preview and update the policy.

Also if you want to move the image slightly to the right side, you can use below one,

If you edit apm.css around line 134 to change...

tablepage_header tdheader_leftcell img {
display: block;
}

to...

tablepage_header tdheader_leftcell img {
display: block;
padding-left: 10px;
}

...it’ll move the image across by 10 pixels.
