Trimming an outlined font glyph using another shape

[On An Island In The Sun]

I am new to Affinity Designer and have a question about something I am trying to achieve in the program.

I am uploading a screenshot of what I'm trying to do and have a question about - which is trim the uneven edges of an object or outlined font glyph using another shape - a circle - so that the glyphs perimeter will be refined and no longer imperfect.

Please view the screenshot for more detailed information.

Thank You.

Boolean operation should do it.
