If it's an insulated double pane glass pac, that's pretty reasonable.

The glass can be replaced in the inner panel

where do you live

measure the visible glass and add 5/8” to that measurement to get your actual size

example visible glass 23.25 x 31.25

first remove the inner gasket

tale a heat gun or torch and run it along the edges

gently pull out the glass and separate the corners

after the old glass is removed, gent gently spread the inside of the channel

the new glass may be thicher than the original glass

inject a fine line of silicon caulk into the lenghth of the channel and slip the glass into it

work all four sides until the corner locks are flush

allow the caulk to dry twenty four hours

Well, he just answered my question. Pella no longer sells the interior panel assemblies, so I may give it a shot.
