You have two options to prevent your player bar from covering up your interactions:
a) Move your interactions up
When you activate the grid, you'll find a green guideline. This is where the player bar appears. Make sure to keep your interactions above this guideline, so they will be visible at all times.
b) Put the player bar under the video
By default, your player bar appears over your video. Follow these steps:
Go to Video settings
Go to Player settings
Go to Select the style of the player bar
Change this to 'Player bar under the video'
